Okay, this is interesting. I’ve been finishing up my collection using AnyDVD. I had a double-sided disc, dual-layer both sides, which had read problems (same results on two different drives). The first side got to 99%, then aborted. The second side got half way (i.e. near the end of the first layer) and aborted.
Out of curiosity, I copied the .iso files to my NAS, then tried to view them on the Hub. Strangely, they gave the identical results as reported at the beginning of this thread. Now I know these were bad .iso files, but I wonder if the identical results has any meaningful significance?
Do DVD discs have something similar to a CD disc’s finalizing? And if so, could it be that the Hub would interpret a disc which wasn’t finalized as being incomplete, and thus yield those results?
