I haven't had an issue with anything like this on my pvr-250, but I have always used mplex (from mjpegtools) rather than dvb-mplex. I'll attach the simple perl script that I wrote to simplify DVD preparation. I have taken probably around 20 VHS videos and put them onto DVD with this without problem, using this script. Either rename the .nuv file to .mpg or edit the script to include .nuv along with .avi and .mpg. The script requires mjpegtools, dvd-author and transcode to work with all of the options.

I've found that some captures (in particular ones from analog tape) have sync glitches in the MPEG2 stream from the hauppauge cards. A lot of tools (mplex, tcmplex, dvb-mplex most notably) cannot deal with anything other than a *static* Audio/Video offset. These glitched streams change the offset in the middle, so they get broken. Here's the first bit of a dvb-mplex command on a chunk of video I know has this sync problem: >dvb-mplex -t DVD -o sync_dvbmplexDVD.nuv sync.nuv Reading from sync.nuv Output File is: sync_dvbmplexDVD.nuv Setting up for DVD mux Opening tmp_as.mp2 for audio demux Opening tmp_vs.m2v for video demux Demuxing 100 % VPTS - APTS = 66ms <snip> Notice that it starts out by demuxing the A and V. Then it calculates the offset (based on most likely the first A/V set), and proceeds to mux it together using that static offset. I've looked at 'replex' a bit, which I think is a fork of dvb-mplex. It appears to do a better job at maintaining PTS sync. I looked into this awhile back (December) and did manage to find a workaround for all this. I wanted to do lossless cutting as well, though: http://www.gossamer-threads.com/lists/mythtv/users/99241?search_string=papen fuss%20sync;#99241 -Cory ************************************************************************* * Cory Papenfuss * * Electrical Engineering candidate Ph.D. graduate student * * Virginia Polytechnic Institute and State University * ************************************************************************* ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
