to which Chas (Charles Martin <[EMAIL PROTECTED]>) replied: >The thing has 6MB of video ram, I'm quite astonished that you can get >it to play at all! I'm gonna call you on your assertion that it's the limited amount of vram that's keeping This Olde iMac from playing DVDs smoothly. >From everything I know, the iMac's video circuitry is acting as a dumb frame buffer simply moving the decoded video from the CPU to the screen. As long as there's enough vram to support the res and color depth, having more vram should make absolutely no difference at all. The graphics chip is certainly capable of throwing those pixels at the screen quickly enough, it's just a matter of feeding it. I'm getting pokey frame rates because the CPU cannot decode and/or deliver the video data fast enough to the graphics unit. The question (for me anyhow): - is the choke point the CPU or is it elsewhere in the system, eg: the system bus? Ultimately I suspect it's gonna be the system bus, though with only a 300MHz G3 in there now I'm pretty sure it's currently limited by that CPU. I can (and will) test by replacing the CPU with a faster unit and see if there's any improvement. BTW, as several pointed out, buying a cheap DVD player is the solution and that's what I'm gonna do. At this point, the Bondi DVD experiment is just to see how what's possible. dan k (with a near-completely NON-Original Bondi 233MHz rev ? :-) ................................. http://macdan.n3.net/ carracho://dankephoto.dhs.org:9700 hotline://dankephoto.dhs.org:9500 ................................. -- The iMac List is sponsored by <http://lowendmac.com/> and...
