thanks for the suggestion but--- I tried to render to quicktime *.mov format, it plays jerky and pixelly. I used 3Mbps Video template with sorenson compression and also tried dv-ntsc with same results and much larger file. do you have suggestion for compression codec. Do I need to change any other settings?
If you need to playback a file on a Ma as part of a presentation, your best bet is to use Quicktime. You may need to render a few versions at different bitrates to find one that will playback reliably on your particular Mac. 3Mb you tried, and apparently your playback MAC can't keep up with that, so try the 1Mb and 512 templates- one of those should work.
