I have a Panasonic DMR-XS350EB - worked fine.
Today the TV (ancient Protech) failed so I bought a Panasonic TX-L32X20B,
theory being Panasonic DVD Recorder/Panasonic TV combo, no problems.
Reality: whilst setting up DVD remote to control TV (it worked fine when I
tuned it for the Protech) I have got the DVD displaying "DVD 3" and the
remote no longer controls the DVD recorder, but does, now, work the TV
on/off, vol, CH and AV buttons.
I've tried the "hard" DVD reset (pressing up-and-down channel buttons, on
DVD recorder, for 5 seconds) - display still shows "DVD 3" and DVD remote
still does not control the DVD recorder - which has started to record a
couple of programmes setup earlier this week.
Which key sequences do I require to get my DVD recorder remote to work
again?

TIA

Keith
