[Mvpmc-devel] Mythtv DVB-T recordings from Australia

[Peter M. <pet...@gm...>]

Hi,

I am having some trouble getting my mvpmc to play my DVB-T recordings.
 I am using a recent CVS version of Mythtv (which works fine) and have
tried mvpmc 0.17 and CVS with the following issue.

When I launch a record to play I only get a black screen and no audio.
 I have tried with NFS and Myth protocol and get the same results.

It seems that the player is having trouble with the Audio, as it can't
seem to make up its mind what type of Audio to play,  the console log
is below.   From doing some digging in the code and adding some
debugging printf's I found that the audio_type was changing between 4,
2 and 5 which are AUDIO_MODE_AC3, AUDIO_MODE_MPEG2_PES and
AUDIO_MODE_PCM.   Is it possible this is to do with the forcing of the
audio stream to "0xc0" for myth recordings?  perhaps Aussie DVB-T is
different?

  I would like to try to resolve this, so any hints on how to debug
this further would be appreciated.  (I have the toolchain all setup
and can compile test dongle.bin's)
