Watching iPod videos on the TV (Need Video Resolution Help)

[Ran]

Okay, so I have some anime on my iPod and I have a thing to where I can play the vids on my TV. Great! I do have a problem tho.

1. The screen resolution makes it so that the subtitles on the bottom are chopped off. The converting program (Videora) is saving it as a 320x240 resolution. What resolution would be similar to a widescreen so that it doesn't chop the subtitles off the bottom? Also, The resolution is terrible on the TV. Again, it's being saved as a 320x240. There are other resolutions I can pick.

640x272
640x360
720x306
720x320

What would be best? I did a ghetto guess by using MSPaint attribute and it seems like 640x360 would be the best. Also, WTF is bitrate?

Thanks in advance!
