On dvb channels where i have bad reception mythtv creates broken mpeg2
files, usualy it results in mythfrontend crashing and unable to fix it with
replex.
Replex just complains about video ringbuffer overflow or something like
that.
I don't understand why mythtv creates bad files, it shoud be able to create
proper files even with some reception problems right?

Coud this be because of problems with TS->PES conversion? Or some problems
with it?

Hmm.. Intresting, i'll have to check that setting too.
My backend is on a crappy mb with via kt266a chipset.
I've always had problems with it, but i thought the remaining picture
problems was also caused by crappy powersupply.

It seems like atleast my dvb-c card is very sensitive to "bad" powersupply.
The powrsupply that came with the case caused lots problems that looked like
bad reception, but when i moved the card to another computer the problems
moved to a different channel.
After lots of experimeting i got a new and more powerfull powersupply and
most of the problems went away.
