I must say that I am a bit surprised by your comment. If you search the archives, you will find very old mails sent by me and involving BenH, Michel Daenzer and other people when I was trying to get my iBook G3 600MHz playing DVDs. It almost played them, depending on the content of the DVD, and with debug messages turned on from xine, xine indicated that my processor couldn't keep up with the task of decoding all frames, but, after a few tweaks, only a few frames were dropped (I don't remember the percentage). I would expect that a few more megaherts in a G3 processor would be sufficient to eventually play the thing and, since I suspect that your 1.2GHz iBook has a G4 processor, the fact that the mpeg2 libraries have altivec support would make this task even easier. Or so I thought. Do you have something like deinterlacing enabled? This would consume a bit more processor than playing the video alone, of course. The version of the linearblend deinterlacer that I contributed to xine is in C only and even though the compilers have gotten smarter since then, they can't be beaten by hand-crafted assembly. I hope these comments help to give you some parameters on what to expect. Regards, Rogério. P.S.: Another thing that you might try to do is to copy the contents of the DVD to your HD and try to play it from there to rule out the possibility of the DVD drive not cooperating. -- Rogério Brito : [EMAIL PROTECTED] : http://www.ime.usp.br/~rbrito Homepage of the algorithms package : http://algorithms.berlios.de Homepage on freshmeat: http://freshmeat.net/projects/algorithms/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
