Is there any benefit from using the new P4 optimized VirtualDub version and if so, I is it as simple as renaming it and placing the executable into the existing VirtualDub directory?

Hi-

I haven't noticed any speedups encoding with it, but all I did was rename it and put it in the VDub Directory as you mentioned. So, I don't know if there's any benefit, but there doesn't seem to have been any harm done.

Same as manano - I haven't seen any real noticeable improvement either. Seems to work just fine though.

From what I understand the P4 optimized version VDub, was actually written to take advantage of the new hyperthread P4's. I've used it for 4 projects, 2 pass divx films, no noticeable improvement, but no probs. A fellow over a Divx forum ran benchmarks using a dual xeon with hyperthread enabled, very small improvement in performance, less than 5 percent. May get better results when codecs can take advantage of hyperthreading.

Very intriguing. Does this distribution support YV12?

Hi-

Nope-still gotta use Belgabor's modded version. Maybe someday, though. I'm sure Avery's aware of the YV12 developments.
