Could be. The encoder used to pause, switch channels and continue
recording, thus creating a small discontinuity in the stream. Now it
just continues recording, albeit without sound. I'm not sure if MythTV
had perhaps some special handling for the old situation.

Almost EUR 250 now. It would be great to double that and I'll pitch in
the other EUR 1000 for the monitor. I'm going for a good 1920x1200
monitor. I once before paid quite a lot of money for a 1600x1200 CRT
which did its work very well for many years. In my experience monitors
are one of the few computer hardware items where it pays to spend
money.
