[mpeg2] Re: problem with setting module option and some audio error

Hi nimeesh,

you should make sure that you use the latest patch from
http://bytesex.org/patches/2.4.23-4/patch-2.4.23-kraxel.gz
as this includes a patch to the card information which is required to get 
audio to work with the BMK MPEX card w/ tuner.

The correct option is "card=23". I also get the "audio carrier scan failed" 
message, but the default of 5.5 MHz works fine for me. After loading the 
driver you have to tune to a channel before using /dev/video{0,1}, otherwise 
you get invalid argument or input/output error. To do the tuning you might 
use the xawtv package. You can scan the channels with scantv (which is only 
built if you install zvbi from http://zapping.sourceforge.net/ before 
compiling xawtv) and switch channels with fbtv (requires a working 
framebuffer setup) or xawtv/v4lctl (both requires X libs to compile which is 
stupid for v4lctl, as this is a command line tool :-().

After that you get a beautiful MPEG2 TS stream from /dev/video1. The drivers 
are rock stable, I've been reading the stream and multicasting it for more 
than 4 weeks now without any problem.

Cheers, Jonny
