Motorola Droid X :: Video Playback - Framerate - Jerky Playback

Been struggling with this since receiving my X. Seems like no matter what player I use the playback is jerky. It's very subtle, almost as if the video is dropping a frame or so every second. I've tried the stock player, Astro, Rockplayer, mPlayer, Zimly, Act, and the list goes on and the problem still persists.

I've encoded (using handbrake) with all of the settings suggested on the boards and have tweaked things on my own trying to find the proper setting, but still no luck. The strange and frustrating thing is that the exact same files play just fine on my 1st gen iPod touch (clearly an inferior piece of hardware) and on my wife's incredible. These encodes are of standard def DVDs at average settings (a full movie is about 1.3gb, all h.264 mp4 files.

I was able to improve playback by rebooting the X and then playing the video, but this doesn't seem like an acceptable solution every time I want to watch something. I tend to encode and watch a lot of stuff on my commute to/from work, and I'd really like to replace my touch with the X, but the media capabilities are falling way short. Considering switching to the Inc as I know it's able to play my media properly, but I'd prefer to keep the X for the larger screen size (though the Inc does seem to feel better when using one-handed). I'm on the fence right now, but if the X can't function as expected then it might be going back. Unfortunately I only have until the 1st to return it so I don't think I can hold out and see if 2.2 fixes this issue.
