I use Handbrake to convert some HD MKV movies to lower resolutions. I also convert the audio tracks to AAC. Everything is fine when the audio source is AC3. But if it's DTS, the result is a sound that has every few seconds a gulp, so that it's kinda choppy.

So I looked for an alternative way to separately convert the DTS track to AAC, but couldn't find anything. Basically, I'm looking for a solution with GUI. I don't want to spend my time in terminal with command lines. It should be quick and easy.

Or does anyone know what the problem is with Handbrake? In Windows, I never experienced any problems. It's only with Ubuntu, even on a fresh install.
