When I convert a file, the app states it will be roughly ***MB big after the conversion, yet it is a massive file.  Am I missing something here?

Example: I am taking a 80MB mkv file and converting it using the TV2 default settings and it will output a 255mb avi file.

I am experiencing this too. Is there any explanation for this? Output size says 43MB but comes out 240MB. Is there anything we can prep better to get those file sizes? Maybe it's the audio?
