You can actually go over 9.8MBps but you can't guarantee that some players won't choke on anything higher. Assuming the OP has not missed any details there's no reason his program should stop him from making a DVD with 8MBps video and 1.5MBps LPCM audio unless the program automatically tries to keep projects at 8MBps or under total. We still don't know what program for sure so maybe it's just a safety feature of that particular app to keep people who don't know what they're doing from making non-spec discs. That's just my guess.
