Having problem after "upgrading" to Windows XP

I just upgraded my OS from Win 2000 to XP Pro and have encountered a very strange problem in Vegas 4.0.

I opened a project that I was working on (originally edited on Vegas running under Win 2000) and noticed now that the audio sounds broken and stuttering and and the video plays back (in preview mode) almost in slow motion.

Can anybody tell me what's up?? I've reinstalled Vegas, but the problem hasn't gone away. For reference, I'm running on a Compaq with a 1.1 Ghz processor and over a GB of RAM.

Everything was working fine under Win 2000, but now it isn't. I'm halfway thru a project and really need to get this problem fixed. Is it a codec issue? Any help would be GREATLY appreciated.

thanks!
Guy

Sounds like it could be the Windows Explorer curse. Next time you see the problem bring up the Task Manager (Ctrl Alt Delete) If you see Windows explorer hogging a huge amount of CPU cycles, by checking the processes tab. If so close it (Windows Explorer) an see if Vegas runs at normal speed after you do so.

Could also be Windows indexing files or doing something else in the background. Again check the Task Manager and see if you can pin it down.

Check your hard drive and verify that DMA is ON.

Thanks for the suggestions. I have checked that my HD's are set to DMA and have watched the Task Manager for anything usual, but haven't noticed anything.

I did notice that the problem was partially solved/lessened when I went to the preferences and unchecked the boxes regarding 3rd party codecs and using Microsoft DV codec. At least now the video appears to be playing at the right speed (previously it appeared to be slowed down by about a third), but the audio still "stutters".

I've not done a test burn of a DVD, but I'm wondering if this is just a preview issue.

Also, I did note that my captures cannot be done without a huge number of dropped frames - basically unusable.

I'm still suspect of my codec situation, but I'm not sure what the problem is. One thing I did note was that if I tried to view any of my captured DV (.avi) files using Windows Media Player, that I couldn't, and the player didn't seem to be able to DL the proper codecs either.

Anyway - any more help that you can provide would be appreciated.

Thanks,
Guy

You may also want to adjust the playback buffering settings.

1. Go to: Options/Preferences/Audio Device Tab
2. Move playback buffering to 0.25 seconds.
3. Play back to test.
4. You may need to experiment with the buffering values to remove the gapping or stuttering

For more details, see Advanced Audio Preferences on the Vegas 4 pdf manual, page 276-278.

I had a while back an audio stuttering when capturing one of my old commercial tapes to put it on DVD. When I played the tape through the preview, the audio stuttered badly and constantly. When I began capture however the stuttering stopped and all was fine. I never gave it a second thought since my capture went good and it seems to be only related to that tape. I have dun other VHS tapes plus captures from my DV camera and no stuttering there. I can't explain the one incedent.

Generally, upgrading from win 2k to win xp is a bit different then doing the recomended clean install. The install routine will try to keep all your older drivers & related software intact, in some cases using various compatibility fixes, and this is most often not a great thing - xp's been out a while, and chances are there is xp specific stuff available no matter the hardware.

In any case, I'd look into removing audio drivers, letting xp reinstall on reboot. Also check to see if xp drivers have been released by the manufacturer and try those. Update xp in any case, and as nec. check all your other hardware drivers to make sure they're the latest versions.

RE: codecs, check out Gspot to see just what codec is doing what.
