Vegas consistently stalls after about 20 minutes of use during playback of 16 or more tracks. Rewinding to the start, it will play a couple times and then stall at the exact came place. Eventually it won't play at all. If I reboot everything is fine for another 20-30 minutes. This is not a problem with my other HDR program (tripleDAT) but I need to work on a 24 bit project. This may be a problem with the way Pulsar/Scope plays with Vegas as another Pulsar/Vegas user has reported the same problem. Any ideas or fixes? My system is a 1.8 P4 Asus P4T-E w/512 RDRAM and optimized for audio.
