Thanks, I do not keep current with video anymore.... > It works so far as I can view the stream...but cannot trigger a > record. You cannot record with any of several application or just one in particular? It seems like I vaguely remember somewhere a howto, to setup a generic small ram drive to 'enhance' the performance of recording on a linux system, but I cannot find the link right now. I use to have problems with resources where if much of anything else was using the HD, even though (record) bandwidth of the mobo sata chip and the drive were no where near the limit, I'd have problems with sustained video recording. Buffer overload? Registers can't keep up? Commerical system all have CAM (Content Addressible Memory) to put the memory on steroids for all sorts of low latency performance capabilities and gains.... I never tracked down that problem nor found a fix that was not too expensive. My guess is it would be a customized, minimized, highly tweaked kernel that would work best for video recording and latency-bandwidth issues, etc..... I was working on multiple medium resolution streams. A singular, hi-res video stream might be even more problematic. It would be an interesting test to put your recording efforts onto a multi disk (raid) array specifically tuned for write speed and see if that fixes your issues? Drop the quality way down and see if you can record then. It that works, then what I just wrote about is your demon. If not, then it's a bug, syntax,decoding or other algorithmic issue.....

Black Crows are one of my favs...... Red-headed woodpeckers are a close second....... (we have lots in Florida) hth, James
