Any way to strip HDCP off of legally-purchased digital files?

[LucasM]

The "4GB limit"?  It apparently wasn't with the blu-ray player, it must have been a particular file that was a problem.  I put the full 4 1/2 GB m4v iTunes film on one of the hard drives I have down in the home theater room, added a second extension ("mp4") to it [adding a second extension rather than replacing the extension so I'd know it was an 'original', not a translated copy], and it plays beautifully.  No 'translation' necessary to shrink it down.  Looks freakin' gorgeous.

Haven't had the brain power to check into any of the other things.

Thanks again everyone who suggested things to help!
