Because you said they look strange I'm guessing they're not in the right aspect for the tablet. what did you use to convert them? when you were offered the choice of format to convert them into, which option did you select (mp4 can have different aspect ratios etc.

if you're not worried about the throw option, may I suggest you download mx video player from the market as its opened and played everything for me so far

The best settings are as follows:

size 1280 x 720

frame rate 30

bitrate 1500

I'm not sure where the settings are in your program, but that's what you should be aiming for.
