I have quite a bad problem in Sony vegas 7.0 . I try to render a video and it will get to a point and it will just go to a complete crawl, maybe about a frame every 10 secs. (generally frame 569 for no apprent reason) . I dont mind this too much as i can levae it on over night. But ive left it on multiple times and it just doesnt seem to render. It gets stuck at a certain percentage and will just move no furthur. The frame counter also goes to 0, when usually it will be counting up the frames that it is rendering. I cant see why it is so slow. I have a 2.4 GHz Dual core intel 2Gb ram and a fast hdd. I have tried rendering it in tons of differnt formats and ntoghin worked. I have tried uninstalling.
