Good luck getting your DVD player to play back DVD-R DVDs encoded with bitrates this high. If it does happen to work then you have a better DVD player than the ones I've tried. My reliable playback threshold with mjpegtools for all my DVD players, tops out at about 7000. I'd say at 7000, 95% of my DVDs work with no problems. Which is why I dropped down to 6500 lately. 6500 is probably very close to 100% reliability on my Phillips 724 and Pioneer DV440 (which are my two main players). Weird thing is, store bought DVDs often go up to the DVD spec max and playback with no problem. Of course the PC DVD players play just about any bitrate from any medium. A lot more forgiving they are. Just a warning,.. try before you settle on 9000+ bitrates. Watch those DVDs *ALL& the way through from start to finish. Make sure your player doesn't trip up on them. --Aaron ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
