RipBot264 and DVDRebuilder work with normal speed for me (Win7 Home Premium 64bit). Any ideas what I can do to speed it up or narrow down what causes the slow encoding?
One test isn't out and out proof, but I did a DVD-RB Pro conversion on my quad with HC 0.23 HC 0.24 May beta and HC 0.24 Sept. beta. I deleted all intermediate files between tests and used the same source with the same settings, 4 instances of HC 2 pass best profile.

The first 2 runs the video processing time was 55 minutes. But the Sept. 0.24 HC beta came in at 50 minutes. I couldn't see any qualitative difference. For @10% speed up it may be worth some copying and renaming.

edit: the other consideration is running 4 instances of HC will be with multi-threading disabled, whereas with AVStoDVD you will be running a single instance with mult-threading enabled if you're on a multi-core. So mileage may vary a bit on that score. Still, I doubt the new HC will be slower in that scenario.
