Both I know all about disc at once and track at once writing. fixed that ages ago. However commercial ones and my own do the same thing. Brian In which case, Brian, my apologies for 'teaching granny how to suck eggs'. :-) I guess you've every right be annoyed with the player. I suspect you're probably not too far off the mark, if at all, in your assessment of the nature of the (self inflicted) problem. Since you mentioned the phrase "ram stick recordings" I presume you meant flash memory stick recordings, as in USB pen drives, implying the existence of a USB socket. That being the case, there's a slim chance that there might be a downloadable firmware upgrade to fix this issue which can be installed via the USB port from a flash memory pen drive. It might be worth doing an on line search before looking for a replacement. You just never know your luck. -- Johnny B Good |

I have for example a cd/dvd player here which sounds excelent but has one flaw any real cd player should not have, it ducks between tracks, so there you are listening to the classical cd with track markers that should not be heard, and hey presto it ducks the sound. I expect more from Panasonic than this, Software operating cds has been standard for may years, so why re invent the thing badly. OK so the player can play mp3 cds and dvds and even ram stick recordings, but all with this strange issue. Can I assume that you are referring to commercially pressed CDs which, when played on another CD player, *doesn't* duck the sound at the track boundaries or are you referring to CD tracks that have been ripped to recordable media such as CD-R and/or CD+R using CD Burning software? It's been well over a decade since I last burnt any audio CDs but I do remember the problem I had creating CDs from ripped tape and vinyl where the audio CD burning software (Nero5 in my case) kept introducing unwanted two second gaps between the seperate tracks very much against my wishes. Prior to slicing each digitised album or tape into seperate wav files, I used to simply burn the whole of each album side (whether direct from the vinyl or a reel to reel tape copy) as a single track which preserved the original inter-track timings. This, however, meant I couldn't easily drop onto an individual 'track', hence my discovering the two second of silence between tracks after going to the trouble of slicing and dicing my digitisations of each whole side of an album. Yes. Either you trim the tracks so they begin and end exactly on the sound, or else you mute the audio (to remove tape hiss or record crackles) and leave in the gap, dividing it roughly equally between the end of track n and the beginning of track n+1. In my case, eliminating tape hiss and/or groove noise was never my aim when submitting a sliced and diced compilation of a digitised album or tape to the burning list. Any cleanup of intertrack groove noise was done prior to the slicing and dicing. Tape hiss was never an issue with the R2R recordings which were done at 9.5cm/s, mostly on Maxel UD35-90B and UD35-180B tape on a much improved Akai GX630DB tape deck with the Dolby NR enabled. My concern was over the *additional* two seconds of silence that the audio CD burning option "so helpfully" inserted between tracks by default. Selecting TaO or DaO (I forget which) was insufficient by itself, you also had to edit out the automatically applied 2 seconds of silence at the end of each track in the track burning list to restore the original track timings. That additional two seconds of silence wasn't a great issue when the track burning list consisted only of 'Side 1' and 'Side 2' but it became an annoyance once I'd decided to slice 'Sides 1 and 2' into a bunch of tracks to allow me to 'drop the needle' onto the start of any chosen track during CD playback. Splitting a vinyl recording that's been made in a studio into individual tracks is a fairly trivial task when the tracks have been laid down as seperate and discreet musical numbers. It's Live Performances or concept albums where the track splitting becomes a little more complicated. However, I quickly cottoned onto the basic rule which was to choose a splitting point where it sounds right for the beginning of the next track even if this is in the middle of the fade out of the current track (with live performances this was typically to the sound of audience applause). Having the splitting point just before the fadeout of the current track has completed doesn't matter since a standards compliant CD player will just carry on playing through into the next track anyway. -- Johnny B Good |

====snip==== I've never known a CD player that couldn't play a continuous "album side" consisting of tracks that run into each other correctly. If it's a commercial audio CD. There's a single spiral track of pits and the track markers are just directory entries of some sort. Anything consisting of separate sound files, whether MP3 or something lossless may have trouble with this depending on whether the player software can load the next file in time and stitch them together before they play. If you've created a 'gapless' audio CD (see below), the player software will quite happily play such a string of tracks without pause just as a cheap audio CD player would (the two second gaps are literally two seconds of silence inserted between the audio tracks by the audio CD creation software. If the CD is burnt at home, even if an audio CD (as opposed to MP3 &c.), may give trouble depending on the mastering software. Once you become aware of the CD burning software's obligatory appending of two seconds of 'silence' to each wav file in the track burning list when using the music CD burning interface, you can highlight all the wavs and select the 'Properties' box wherein you can then alter or remove this two seconds of silence en masse (this was the case with, air, Nero5 - it might be a little different with other CD Burning software). As far as I can recall, you also had to choose either DaO or TaO -I forget which- in order for this to work. A standards compliant CD player will play a suitably mastered audio CD as one continuous track, including any two second periods of silence that the CD mastering software may have appended to each of the individual wav files in its "burn to CD list". Brian's Panasonic CD player is clearly not standards compliant, hence the inter-track ducking of the audio playback level. -- Johnny B Good |

I think that is what he's referring to, and I can confirm I've observed the same effect. A typical pop album will be a collection of separate songs with brief pauses between them, and a great many classical works will also be divided into different "movements", usually intended to be played with pauses between them, but occasionally not. Even when movements of a symphony or concerto are played without breaks, as their composers intended, it's usual for CD recordings to include the same metadata markers as for separate tracks, and when a player handles this correctly you will see the indicated track number change but without hearing any interruption to the music. Some players can handle this and some can't, but unfortunately there doesn't seem to be any recognised specification or manner of indicating it, if it's indicated at all. The only way to find out if a player you're considering purchasing can handle track changes in the middle of the music would be to take a copy of a suitable work, e.g. Beethoven's 5th, to the shop and ask for a demonstration.

Yes I'd be happy with just a set top box as long as it had voiced menus.
I am not sure what happens to the pictures of course but some people seem to be shooting themselves in the foot by using powerline internet networking which with some sets seem to upset them rather a lot. Obviously no enough isolation from mains borne crap. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff... Blind user, so no pictures please!
