I purchased a number of videos yesterday from iTunes, and, because of the horrid video encoding, and the fact that both iTunes and QuickTime are memory-hogs, my slightly less than average computer is unable to play the files without the video lagging to the point of being unwatchable. I've shut down everything extraneous that was running on my computer and tried playing the files in QuickTime, but after about 2 minutes, the video began lagging again.

I normally have no objection to Copy-Protection on files, but this is ridiculous. I paid for the videos and I want to be able to watch them. Tunebite obviously won't work because it depends on being able to record from iTunes, and the fact that I can't get the video to play at any watchable speed is my whole problem. Is there anyway, regardless of what hoops I have to jump through, to remove the protection on these videos so that I can play them on one of my less bulky players?
