THe UnleashX dash has screen positioning options under System > Settings.
What about the games themselves are they off centre as well? If not there isn't much you can do which is just going to affect the FMV. FMVs in console games are often all over the place and can be letter-boxed, window-boxed and positioned left/right/above/below centre.
I know from my own experience with a Sony WS TV that the factory settings for screen centring and geometry in general can be way off ideal. Overscan could be hiding the problem and that might explain why you only notice it with non-full screen FMV.
Going into the TV's service menu (not recommended for newbies) or employing a TV engineer (expensive) to do the same might solve the problem.
Only a suggestion which may not be acceptable for you but you don't sound too bothered about the dash you're using: I've found that using UnleashX to centre/size the screen seems to apply to anything else you boot from it ie. apps and games. Swap to UnleashX and run EvoX as an app.
The other obvious alternative is to do the same but using XBMC as your main dash.
I changed the default dashboard from EvoX to UnleashX and used the screen calibration, but it didn't seem to make any difference. The game I noticed the problem on is Justice League Heroes. It's not so much that it's off-center, but rather the sides seem to be wider than the TV screen, and it's during gameplay. I'll try another game that has icons near the edges to see if they're cut-off as well.
Funny you should mention a Sony WS TV, because the TV I'm using is a Sony WS TV (HD CRT). Unfortunately, the TV only has adjustments for tilt and height adjustment... not width.
