Not really - this is a function of the system rather than anything else - when you see the drop count (the last digit on the line) increasing, then you are approaching your systems limmitations, and playing around with size/quality can help. > Actually more genreally, now that I have it working, which of the knobs > should I try tweaking to optimize it's operation? Most things are pretty optimal already - you may need to play with the DivX quality (-dq switch) to get the best possible quality for your CPU power. -justin _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
