Vegas Movie Studio 10 - Playback Error

[pmk396]

Hi all,
I don't know if this problem has been raised before but I have had Vegas Movie Studio 10 Platinum Suite since February and up until now it has been working fine. The past few months I have been editing a short film (20-25 minutes long it total) that I have been working on and most of the project is edited with the exception of one or two scenes. However, I recently noticed that while editing and using the playback, a message pops up stating "An error has occurred during playback. The device specified is in use." The only option is to click the "ok" button, shut down Vegas, open it back up and continue from where I left off but after a short period the same message will pop up again. It is getting really frustrating. I researched the problem and a lot of forum users state that it is generally a problem with the audio and the solution is to go to Options> Preferences> Audio Device and change from "Microsoft Sound Mapper" to "Windows Classic Wave Driver". I tried this and I still have the same problem with the playback.

The only thing that I can think of is that there is quite a lot of data on the timeline between video clips, audio clips, etc and I'm assuming that the programme is crashing due to it trying to process all this data through the playback function. The clips are quite large (in data terms) as they are in ".MOV" format recorded from my Panasonic GH1 camera (unhacked). I have opened a new project windows on Vegas and it works fine, so I'm guessing that the problem is due to the amount of data that the programme is trying to process on the orginal project.

The only thing I can think of doing now is to edit each scene individually on it's own timeline and render it. Once each scene is render, the plan is to put import scene onto the main timeline and render them altogether into the completed project. I'm am just concerned if it is possible to lose quality when footage is being "re-rendered". Can anybody shed any light on this for me?

I've been having the same problem with Pro 10 lately (the past few weeks), even with only 1 (rather long) clip on the timeline.
In my case, it happens when I start up a second instance of Vegas.
The machine is not connected to the net so Windows updates can't be blamed.
