YES ! I have only one movie on DVD, and bought a DVD player just for it.
It was very weird. The first day I tried it, it was smooth/perfect. The
next day, it would stutter, the day after, would be smooth again, the
day after again, back to stuttering. I have no idea what wrong. 
It was on my desktop machine though, not a laptop like you, but desktop
motherboard have ACPI too, so might be relevant.

I would love to hear what the problem is !
