Zealand DVB-T source)

playing with mplayer latest svn.

Mplayer does not like the Audio format
gives lots of error below and video will stop (can forward to different
parts of the video with forward and reverse but audio will look shortly
after)

Playing /files/TEST/tvnz7.ts.

and video stalls and seems audio goes into a loop. Seems this problem
has been discussed in the past?  With -nosound the video plays ok 

note in source:

  //dunno the payload format for versionA
            fprintf(stderr, "versionA not supported\n");
            return 0;


 Is versionA format need writing for mplayer? even if, should the audio
go into a loop?



Thanks
