DVD Shrink freezing at 99%.

[Discrepancy]

Here's what happened:

I was burning with DVD Shrink onto a DVD+R, and it got all screwy at 99%. Ok, I was playing Need For Speed Underground, which probably wasn't the most intelligent thing, but n'yeh. Windows Task Manager didn't even say it was running, and it was greyed out and everything, so I had to restart to end it. Well, the disc got screwed up, and bleh, there goes a DVD+R.

Now what was strange was well was while the DVD Shrink didn't say (Not Responding) at the bottom, I couldn't eject the DVD from my DVD burner until after I restarted.

So I want to burn again, and this time I figure i'll keep as little possible running and be a good boy instead of acting like a moron and playing a game while trying to burn. Everything is going fine. Except now it's at 99% and Not Responding. And I don't know what the heck is wrong exactly. DVD+R discs aren't cheap and this is like, argh. I don't have much money, so messing up DVD+R's isn't a good thing. Also, the DVD drive won't open, even going into My Computer and selecting to eject.

So erm, any tips? Anyone know what's wrong? I'm using DVD Shrink 3.1 to make a backup of one of my DVDs, so I was going from the disc. This has happened twice from the same disc. However it messes up during burning (As I said, both times at 99%) and gets through encoding just fine, so I don't think it's the disc being ripped that's the problem.

My computer specs:
Windows XP Pro, Radeon 9800 Pro, 1024 ram, 186 gig hd, 2.8 ghz H/T Pentium 4 processor.

Someone please help.

Just for clarification, i'm using Philips DVD+R discs. And they've worked before this, and aren't low quality by any means.

it could not do any damage to re-install dvdshrink
