OK, here's a couple bugs I've seen since installing an hour ago:
Rip one DVD, everything works fine. Try to rip or copy a second DVD, and things go south. First, the program will fail to detect the size requirements for the second disc. It reports a 100% fit to DVD5, even when the data far exceeds DVD5 capabilities. Second, once the rip starts, the program will crash. It will not rip two or more DVDs in a row without crashing; each DVD requires a restart of the program.
The second crash tonight prompted the program to submit a report.
Windows XP SP3, up to date, 2Gb RAM.
