I have read about this error happening on retail discs but nothing on "homemade" discs.
I created a DVD ( with DVDAuthorPRO if it matters ) a while back.My brother wanted a copy of the disc but for whatever reason the software wont read it.It plays perfectly fine on my PC and home standalone player.Is this an issue of finalizing the disc?
DVDShrink seems to have no problem, although it is VERY slow at ripping.

Why would I be getting this error? It's the popup wanting optional info about the disc and to send IFO files.

Please let me know what other info might be needed to help solve issue.
Thanks in advance
