Hard to imagine these errors just being media related. I just started having the same error, specifically burning an ISO file with MDS. I usually don't have trouble with VIDEO_TS folders. My next attempt (coaster) will be with the ISO extracted to VIDEO folder.
I wish someone here could explain the errors in detail, here's my log:
