ive tried this... but when i drag the 10 bit file into the bat file the dos prompt flashes and disapears.. im going to try your zipped version just incase i did some thing wrong.. Thanks
Xvid4PSP works perfectly. It's free too, and it has no problems with 10bit to 8bit. Also, you learn a bit about AviSynth scripting from it, which helps if you're wanting to put say, ordered chapter releases together and encode to another format.
