Odd rendering pauses and jump-to's

Hi-

Now have VMS9.0B and was previous user of VMS8.0d.

I never had problems in 8.0d like this (had building peaks error with M2t files in 8.0, which 9.0 fixed), but on a few videos I've put together now I render off (as xVid AVI, if that matters) and the resulting video may play fine for a while and then it hits a spot and just stops............. then maybe a few minutes later it will take off again at-the-right-spot as though it had never stopped/paused for all those minutes.

Another problem I've seen in 9.0b is that the video will render fine up until a scene split and then the very next frame will be from a place further back on the time-line and it will render on from there until the time-line ends -- but the ending point is the time-line time wherever that brought the video too. In other words, if I have a 3 hour video and the video at hour 2:00:00 jumps back to hour 1:00:00, the last frame of the rendered video will be that found at hour 2:00:00.

Another oddity is if I drop a video into the time-line, let the peaks build, then want to edit out (delete) the first few minutes of the video, which I do by splitting the video out at the frame I want and deleting the preceding portion and moving the video against the 0:00:00 mark. This will render the video... sometimes... in unpredictable ways.

This is all very weird and I just don't get what it is that is causing it.

In a previous edit I got around one of these when I zoomed in and found there was a frame dropout or something on the master tape sent to me by the video guy (he renders out a DV tape to me after doing some work on FCP on a Mac, so it wasn't in my capturing from tape) and I had to split the scene there and do some cut/splice/delete mess to have VMS go through this as if it was a new scene inserted there.

Maybe that's a clue -- I don't know. VMS8 would never do this. If the peaks built, I could edit/move/delete the clips adnauseam and whatever was on the timeline became my xVid avi.

Sorry for the long post, but at 8-10 hour renders to discover the video is bad, I finally figure to ask the experts (you're all experts, right?). : )

Do you have any antivirus, security software running in the background? Are you using Windows Vista or XP? Also, are you using an indexing software (for example the search indexer in Vista or in Nero)?

Next time when you render, have a look at the Task Manager to see what application is taking up your cpu time when those glitches happen. My hunch is that another software is using that time and interrupting Vegas.

Having said that, I have yet to see reports of that here or in my (somewhat limited) experience with VMS 9b.
