OK, it's now March 2010, but for the benefit of anyone finding this discussion via a Google search the way I did, I'll answer the question:
Yes, it does!
Details: I have a JVC DR-MV150 which is a VCR/DVD recorder with a digital tuner and an HDMI output. I've been recording TV shows on DVD-RW's and playing them back on that machine, but sometimes I'd rather play them on my HP Pavilion laptop with Windows XP instead. Initially, sometimes it'd work, sometimes it wouldn't. When it didn't work, the laptop not only wouldn't recognize there was anything on the DVD-RW, it wouldn't even recognize it was a DVD! It'd tell me there was a blank CD in the tray and ask me if I wanted to format it!
The above discussion compelled me to try re-initializing the DVD-RW's in VR mode. I tried that and then they played just fine in the laptop! When I checked the DVD-RW's on hand, I found that a couple of them were already initialized in VR mode, which is the reason it sometimes played before. I have no idea how they ever got into VR mode, since this player automatically initializes new DVD-RW's in Video mode when first loaded -- you have to manually re-initialize, and I never did that. It's a mystery.
I will add one other observation: I've been recording these DVD-RW's in LP mode, which gives four hours per disc. On my 50" Samsung plasma HDTV, I can't really tell the difference from SP (2 hour mode), they both look pretty good to me! But on the laptop, the picture is considerably worse. It looks kinda like a JPEG with too much compression, all blotchy and frayed around the edges. I haven't tried the SP mode, so perhaps it's just the LP mode that's the problem, but I don't understand how the HDTV wouldn't have a problem with it while the laptop does.
