Comment(by mythtv at miwers dot dk):
Shane's patch didn't do the trick for me either. However, I also tested
with Tino's patch in order to reproduce the error faster (every 2 minutes,
for "Unknown" shows), and here's my findings:
I can only reproduce this problem on my IVTV tuners. It's a Hauppauge
PVR500 dual tuner card.
I also have a WinFast DTV2000H, which is a hybrid analogue/digital tuner.
This card uses some different modules (not IVTV), and using this card will
not reproduce this error.
So...
card1: IVTV: PVR500-1: reproducible[[BR]]
card2: IVTV: PVR500-2: reproducible[[BR]]
card3: V4L: DTV2000 A: not reproducible[[BR]]
card4: DVB: DTV2000 D: not reproducible[[BR]]
A theory of mine is, that the MPEG2 stream of the ivtv tuner is different
than that generated by the DVB card, and may contain some "bugs" that the
frontend player can't handle...
Another theory (and an educated guess on mythtv recording): During channel
change, the card is reset, and a new MPEG stream with headers and stuff is
generated. But during program change on the same channel, the card is not
reset, but recording happens to a new file. Won't the player be missing
some MPEG headers, which causes it to freeze?
Maybe those two theories combined are the reason that only my IVTV tuners
freeze and the DVB tuner does not?
I have kept two recordings for each tuner type, if someone would like to
make a comparisson between them. First recording when entering the channel
and the following file on program change. Contact me by email for a link
to the files (few hundred megs)
