Benq +R scans

Here are scans of the first 3 DVD’s of a 50pk I purchased at Future shop. Seems 1 and 3 are ok, but #2 freezes around 1:35 into the movie. I’m fairly new at ripping so I’m wondering if these inconsistancies are normal.

Also, when I set the booktype to DVD-ROM my player will not recognize the disc unless I leave it at +R. Shouldn’t ALL players be able to read discs set to DVD-ROM by default?
