When I bring up Tools>Burn DVD Image it immediately starts computing an MD5 checksum for that image. When I actually say "start burn" after checking the "verify written data" option, it burns the dvd, then immediately computes the MD5 checksum of the image (again!) to compare with the MD5 sum of the DVD it just burned. If I tell it to make 2 copies of the same ISO image, it recomputes the MD5 sum of the image file over again for the 2nd copy!

Even with fast disk drives and fast computers, this is a time consuming operation, and it sure seems like computing the MD5 sum of the image file just once would be a perfectly fine thing to do (if someone is paranoid about the image being modified during the burn, then compute the checksum of the image file *after* reading back in the DVDs and computing their checksums).
