I was just wondering what sort of things can be done in Virtualdub to try and get a little better performance (few frames dropped for example). From what I have read, in Virtualdub bigger buffer or bigger chunk sizes do not mean better performance.

I would be interested to hear why that is the case...what is the science to figuring out the optimal buffer settings etc.

I'm also confused as to why whenever I use Huffyuv with the "best quality" setting that I drop a ton of frames and my CPU usage is not maxed out. I've got a 120Gb hard drive, unless I go with a SCSI or RAID setup I just don't think you can get much faster a drive. What's up with that?
