Something that nobody has mentioned thus far in this thread is that it is NOT mp3 OR PCM that the PVR-350 outputs -- in both PAL and NTSC formats it puts out MPEG-1 Layer II audio. Technically speaking, this is only DVD-compliant for PAL players, however, I have yet to find an NTSC player that refuses it. PCM audio is compliant in both systems, by the way. Your post raises the question though; why are you even doing this? The output is already DVD-compliant if you record at 352, 704, or 720 x 480 (or 576 in PAL countries). MythTV simply names the MPEG file .nuv -- dvdauthor will take the file directly. If you have tried authoring the file directory and have an (NTSC) player that refuses the audio, congratulations, you've found the NTSC player that I believed not to exist. ;) Demuxing the audio and video is just asking for trouble -- PVR-350 audio and video streams aren't guaranteed perfect sync, but are kept that way through PTS data, which is lost when you demux. -- Ian Trider [EMAIL PROTECTED] _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
