Best settings to play a divx movie using TV out cable

[augie0041]

I play Divx movies all the time on my Touch Pro, I love how it plays the movies in its original resolution and we dont need to convert them to play on the small screen.
However, when I plug in the TV cable to a tv-set, the movie begins to stick and jump around and becomes unwatchable.
I tried turning on airplane mode to reduce CPU or whatnot, no help. I eventually figured out that choosing Quality - Low from the Video Options at least played the movie smoothly, however the movie was obviously of lower quality. I felt cheated, because I'd rather down convert the original movie (and save space on the memory card) then to play the movie at half quality.
What do you think, what settings do you use to get the most out of using the tv out cable?
