I have had very disappointing results trying to use CloneBD. After the bugs are worked out, I hope it will be able to handle re-encoding of BDs with interlaced VC1, which is not uncommon on BDs of TV series. To the best of my knowledge, no other products on the market are able to do this (DVDFab, BD-Rebuilder, etc.). In the meantime, I think I will stick to using BD50 blanks. The price is now very affordable, making video re-encoding unnecessary. They also save a lot of time, since quality video re-encoding requires so much computation. I can rip and burn a complete BD50 in less than an hour using an older computer.
