The M22s are good speakers but don't have lots of bass. If you haven't calibrated speaker levels properly, that could be a factor. Personally I like my bass at about +3db above the calibration point.

I have the "Hell Freezes Over" DVD, and it's very good. However if you want the best, try the Hotel California DVD-A. It will play on most DVD players. It's one of the best surround mixes I've heard.
