Hey all, I have a e6600 OC to 3.1 GHZ and am Using dvdFab to encode my DVD collection to an Xvid Avi. So here is my problem. I can't find out how to get DVDFab to use the full power of my CPU. Currently it only ever goes up to 50% usage no matter what clock speed I am using. I have tried updating Xvid to a recent CVS build, even editing the default xml files to try and tell the Xvid Codec to use multiple threads, but not dice.

So how can I use my full CPU Power? Do I need to use a different program? DvdFab works well and I like the simplicity of it, but I would prefer Speed over Simplicity any day. Im not scared of getting down and dirty and messing with config files or whatever. I would just like to use more then 50% of my CPUs processing power when encoding. Any help?

No multithreaded implementation will ever beat multiple independent encoders running in parallel. So if you have multiple dvds to encode and each one only uses 50% cpu, just encode 2 at once.

Is it common then for Multi threaded applications to only use 50% of the CPU? Is there no program out there that can use more of the power? Ohh well, thanks for the advice anyways. I have the full series of MASH coming soon so Ill have a couple of instances going :)

No, but it is common for multithreaded xvid to use only 80%, so even if you did get it to work, multiple instances would be better.

So do you think it is possible that DVDFab is TOO threaded? Or do you think that it is not taking advantage of Xvids multithreading. As I recall, Xvids threading is only in the CVS tree, so it is possible that DVDFab is not taking advantage of that, but if there is a way to get it to use Xvid's threading I would love to know. Thanks for the responses btw.
