Media questions

I just recently got the eXpo and overall I am pleased with it. Although I am still learning about it. I have a question about media playback. I have been using certain mobile media conversion programs lately to try and play movies on the media player. The only problem is that when I play back a movie it seems a little sluggish or jumpy. Besides being a WMV file are there other things that I should change regarding movie file (dimensions...  ect?).......  Thanks

Not sure what kind of issues you are having, but my media plays fine. I've played a 1.2GB video formatted in 1080p for my ps3 on the phone with no issue. Resolution has not been an issue with this phone as it was with my tilt. You didn't say what conversion program you were using, but you might want to try Pocket Divx. You basically use templates for certain phones or you can make/save your own template. You go in and set your vide size and audio properties and then save it. It works great.
