I've used the latest version of ProjectX on my QAM recordings through my HD3000. When I play them back through mplayer the sync is fine. ProjectX will also let you do basic commercial cutting (it only cuts along GOP groups, so its not perfect). I use avidemux2 to do my commercial cutting, and then I encode to XviD for backup, but it can do DVD format as well. Avidemux2 does require re-syncing the audio, but its a trivial matter. The only problem avidemux2 has so far is with mixed progressive-telecine shows, the only of which I've encoutnered so ar is Supernatural, but I'm sure theres more out there. For this I use mencoder with the pullup filter to fix the telecine and do my cropping and resizing, encode to huffyuv or xvid at is highest quality settings. Then I open it in avidemux to do my commercial cutting and final encode to XviD. So far this process has worked 100% for me. Also, Considering your dropping in resolution eitherway the quality loss is not a real issue, either way the encode will look as good as possible for the format you choose. I've found my XviD encodes are about 95% as good as the original stream when played back on my 21" monitor, which, considering I can fit a 45min show on a 80min CD with the original AC3 audio, I figure thats pretty darn good ;-) I would like to know if you get this working with your PVR card though, I plan on writing a how-to for the avidemux2 documentation and if I know the PVR output works with the process I can put that info in. Hope this helps! Steve _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
