What is it doing? Are you recording in SLP mode and then it's playing them back in SP mode? I'm sure you could manage to override this, or at least force it to play EVERYTHING in SLP mode if you're good at fiddling around with things, but it's really not worth the effort unless you want to do it for fun.
You can get combo VCR/DVD players for $100 easily. WalMart has VCR's for $39 (although WalMart is evil and all that).
