I'm not sure why, but TMPGEnc locks up every time I try to use the Merge & Cut feature in MPEG Tools (SVCD-compatible MPEG-2s). I'm aware of the trick about playing a few seconds of preview before trying to set cut points, but it locks before I can even get to that point.

Specifically, I can load the file, but when I highlight the loaded file and click on "Edit" (or double-click to do the same thing) it freezes every single time. I read somewhere that if you enter the name of the new file prior to clicking edit it will avoid this, but that had no effect. I'm currently using TMPGEnc Plus Version 2.521.58.169, but I've had the same problem with other versions as well. I'd greatly appreciate if someone has a fix they can provide.
