Adobe Media Encoder problems
 

So I'm using CS5 encoder now to turn some clips from wmv to flv and while one clips works the rest just instantly crash and lock it up, fucking frustrating, has anyone else ran into this issue with clips just locking it up as soon as you add? The first clip that did work is from the same camera, same format, etc etc

Sounds like a pretty nasty bug on the CS5 side. Since Media Encoder will use the Microsoft WMV APIs, be sure you have the latest stuff from Microsoft (though CS5 should have installed it). I'm assuming you're on Windows.

There have been reports of stability problems with Media Encoder for CS5, so you could try the Adobe forums to see if they have any workarounds.

To verify the problem isn't in your specific WMVs, collect a random few from the Web and try those.
