[mythtv-users] Frames per second?

FWIW, it took me considerable time (a few days! :-( ) to get my
SAA7143-based card (Terraterc Cinergy 400 TV) to work as well. E.g.
there is a switch oss=1, which seems to switch sound support on (at
least that's what was needed here), but it defaults to off and is
nowhere documented, I found it in the source code (!). I was unhappy, to
say the least.
Here is what I had to do, maybe you want to add that to any possible
how-to or list, given that the saa7134 cards are a good deal now (better
than bt878a, probably):
1. Use kernel 2.4.20, enabled sound and V4L support, but no specific
drivers (IIRC).
2. Use latest (0.2.7) driver from <http://bytesex.org/saa7134/>
3. Add the stuff below to modules.conf (or /etc/modutils/tv,
removing /etc/modutils/bttv and then running update-modules)
4. Any other things I did during these days but forgot now
However, I still have problems with the sound occasionally. It seems
that the first time watch livetv or something records after boot, I get
no sound at all (lost a few episodes, incl. Enterprise, to that :-( ).
If I go to LiveTV, exit, go to LiveTV again, it usually works.
Sometimes, I get no sound at all and have to reboot. I have no clue why
this could be.
modules.conf:
# i2c
alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
# saa7134
alias char-major-81 videodev
alias char-major-81-0 saa7134
options saa7134 oss=1
pre-install saa7134 modprobe tvaudio
post-remove saa7134 rmmod tvaudio
