I've been playing a few DVDs with plain vanilla libdvdread-0.9.2,
libdvdnav-0.1.9 and a52dec-0.7.4 and it worked pretty well.

The only problems I had were with DVD menus on DVDs that have NTSC
material in letterbox format. There the highlight areas were often
displayed incorrectly because the offset in cDvbSpuDecoder::ScaleYcoord()
was set to a fixed value of 72 (which is correct only for PAL).
Setting this to 60 fixed it for NTSC (this fix will be in VDR 1.2.3).

Of course, there still is the problem that some DVD menu's still images
are not displayed correctly, but that's a general problem which I have
no solution for, yet. I did several test, for instance, with cDvbDevice::StillPicture()
and defining VIDEO_STILLPICTURE_WORKS_WITH_VDR_FRAMES (so that it would use
the driver's still picture facilities), but VDR's I-frames just don't (always)
display that way. I'd really like to know what's wrong here...
