The DVB MPEG stream is MPEG-2 but its wrapped up in a container which syncs the audio and video. You do need to unwrap the mpeg before you can transcode to mp4 or whatever. The complication comes from resyncing your audio and video streams, hence the problems you are finding. I understand that 0.19 will have an integrated mpeg exporter (actually I think the devs ae going to just record straight to MPEG2) Here is write up on my website on exporting your dvb streams and saving. http://acaciaclose.co.uk/28654/124502.html Mike C _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
