m2t file corruption

I've got a problem and hoping for some insight. I have a number of 720-24p HDV files that are now playing back stuttery. This is in Vegas7, 8 and 9 and in VLC. They were fine before. I've copied some files to a different hard drive and one was fixed and the other is still stuttery.

I've never had problems with mt2. This problem is kind of melting my brain. The only change I've made to my machine was to install Raylight to handle some HVX clips.

Any info would be awesome.

I had issues when I stored my files on the same drive as my paging file. Once I figured out what I did, I moved the paging file elsewhere and all was well.

Have you tried restoring your system to a time before the Raylight install to see if that is the culprit?

Paging file is on c drive, media is on F and H so good to go their.

Just called the Raylight guys (You can actually get a hold of them by phone!) they said it was pretty doubtful a Raylight problem. Sounds plausible but with computers it always seems to be the last thing you changed - thats the problem...

will try a few more tests. Thanks for the post.

What about automatic updates (or any recent updates to codecs)? Have you checked any of those? Just thinking out loud.

If you try it on another computer does the stuttery file not stutter?

Here's a suggestion...

1) alt-cntl-del -> start task manager
2) click on the "Processes" tab
3) make sure "Show processes from all users" is checked.
4) click twice on the "CPU" column (to sort in descending order)
5) start your playback
6) check to see if any processes are hogging the CPU.

Good Luck,

Thanks for the suggestions guys, much appreciated.

just an update, conversion of the mt2 files to cineform seems to be doing the trick. I'm also putting the converted cineform files on a different drive. The brain melting part is that the troubled mt2 files were rendering as stuttery. They used to render just fine... I'm used to preview stutter from Vegas but I've never had it manifest itself in the final render before..... also did a search and came up with nothing on this specific problem.
