Hi, guys. A couple of weeks ago I just bought a new computer, and got Vegas Movie Studio 9 to do some videos. First video worked fine, went off without a hitch. I'm having problems with the second video. Everything I captured with my camera works perfectly, but when I use clips that I downloaded from youtube, it gets random errors. Sometimes they look fine in the trimmer, but then when I drag it to the timeline, the video might go to the red screen, or the audio might drop out or go out of sync. Sometimes a perfectly working file might look all screwed up in the trimmer, with large patches of audio or video missing. I updated to 9.0e, but that seems to have only made it worse. For this particular project, all these files were working fine, until one day, all these problems just came up.

If it makes any difference, I use keepvid.com to download .flv files from youtube, and then Movie Converter v4 to convert them to .wmv files, since that seemed to be the format that worked best when I first started using Vegas Movie Studio. I appreciate any help you guys can come up with. Thanks!
