Does anyone use dxtory to record?

I've used it for a while, but since I re-built my computer I can't seem to get it to work again.

I'm using the same codec I was before (x264) with the same settings, but now it won't record anything with more than one client open.

I press the record button and it shows the recording fps:file at 60fps:0 file. Then when I tell it to stop recording it shows the 60fps:fin and then does nothing else.

any thoughts?

I don't use fraps anymore because 1080p recording is like 2gb for 30 seconds :/
