It seems to be fixed in 0.3.8, but previous versions, probably just in the 0.3.7x line would generate "bad" mpeg files. The PVR 350's hardware decoder didn't care, so I never noticed, but projectx cares, and slows to a crawl when it encounters such a "bad" mpeg file.

You can them Burn DVD's in close to or better than real time at least I can using a 2.4Ghz Celeron. What would be really cool would be a hardware transcoder card that could not only decode the most popular formats but also re-encode them to a choice of formats in real time or better. My standalone dvd/hard drive recorder can do something similar by only MPEG2 to MPEG2 formats so it must be possible.

So, I bought a nice 8x DVD+R burner for cheap, thinking that my biggest problem would be speed issues when I burn from a file stored over NFS. But it turns out that is the LEAST of my problems! I haven't even gotten to the point where I can attempt a burn. My poor 733mhz CPU is still transcoding my PVR 350's nuv file up to DVD resolutions! By my calculations, it's going to take about 6 HOURS to transcode a 30 minute show... man and this project-x thing is running java of all things, which certainly doesn't help the speed! So how do you folks go about burning DVDs? Do you just have massive 2.4ghz processors and burn over night, or am I doing something incredibly wrong? -- Jesse Guardiani Programmer/Sys Admin [EMAIL PROTECTED] ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
