Video problem after update

I downloaded the new update the other day and now some AVI's that were previously 100% fine stutter and stop with the
"status code 69-80070057
The video file is corrupted. Or, the content may not be supported" error message. Any one else seen this?

Just did a quick search and found this over at teamxbox:-

A post suggest's converting the files to mp4's using this link:-

cheers fella. yeah, i did see that link myself on a google about. however, i'm not going to be converting the best part of 500gb of avi's!
I'm just confused that everything was fine before the update, but i read the ypdate was literally nothing but preparing the box for the new dashboard. no coincidence though, it happened right away.
oh well.

There maybe a 'fix' in the next dashboard update. Good old Microsoft eh?

Here's hoping. Kinda disappointing to have all my (and my kids) vids suddenly stutter and crash after playing perfectly fine for the last 3 months.
