iPad RushPlayer+ crashing on .mkv playing?

It will play mp4's flawlessly, but when I try playing an .mkv file, it will allow me the first 5 seconds or so in perfect quality, but if I tap the screen the controls don't come up. And 5 seconds after playing, it crashes back to the homescreen.

Anyone else have these problems?

I don't have my other tweaks installed, just:

Activator
Adblocker
Airblue Sharing
AppList
BigBoss Icon Set
Cydia Installer
Cydia Translations
Erica Utilities
Evasion 6.0-6.1.2 Untether
f.lux
FullScreen for iPad
iFile
iSeries Shows
iTransmission 3
Mobile Substrate
Safari Download Manager
Springtomize 2
Substrate Safe Mode
SwipeAway

All of these tweaks are in their latest versions, and no cracked apps at all.

What gives?
