Hi Ron, Here's what I do, I hope it helps. I generally create a DVD with 6 or 7 different clips that I output from Cinelerra as Raw DV files. I add up the total running time of all the clips (the one I'm currently working on is 6 clips totalling 71 minutes). I take that over to http://www.3ivx.

Thanks for that. I suspected that bit-rate was a factor, too. I don't actually specify bit rate anywhere; I've just followed the cookbook. Bit rate is implicitly set, I expect, by the '-target ntsc-dvd' option on ffmpeg; and I suppose that the 'YUV4MPEG Stream' and 'ffmpeg pipe' settings determ

Not strictly a Cinelerra issue, but I hope the community can offer advice: Do you have experience with delivering longer-than-half-an-hour programs on DVD? 1. My intended audience is small (20-50 copies), using ordinary home (NTSC) tv playback gear. 2. I've been following the workflow in the Cin
