Slightly OT, but in regards to the 5D MKII's 4GB limitation, is that to say that you can only record 12 minutes at a time? or is it to say that if you have an 8GB CF card, you can record 24 minutes seamlessly, but it will have created two 4GB files on the card? Is there any limitation on recording length as far as sensor heat and image quality is concerned?
