How can I get screencaps from a DVD without putting the disc in the DVD-ROM drive?

Because my drive went caput and I can't afford a new one.

I'll read any 답변 당신 can give me, 또는 any 링그 that 당신 think might help, no matter how complicated, ridiculous, 또는 expensive the solution might be. (Hey, I said I'd read them. I didn't say I'd try them all.) But don't say to take a picture of the TV screen. I've tried it. It doesn't work. (Yes, I've gotten that desperate.)
