Shut all 7.1 off and anything above 96khz off.

The PS3 will not upsample movies but it will upsample CD's. If I recall correctly there is not a seperate setting for CDs.

But you don't want to set it below 96 becuase that will downsample some BD discs.

Every BD movie I've played has played fine (30 ?) and almost every one has defaulted to a lossless format. I'm almost to the point of not bothering to check anymore because it has been on the correct format (best) on every disc.

Correct HD621 can only deal with 5.1 channels at the moment.

If you think listening to music is fun, try learning an instrument.
