Yes, I can confirm that using that stream type for recordings produces mpg files with the VOBUs required for DVD-Video, UNLESS you also have VBI enabled (which adds the driver's private stream with sliced VBI data). But if you don't want to capture closed captions or teletext and don't enable VBI (forget the control for that), you can give the recorded file to a patched version of dvdauthor and it will be happy. Just be sure the resolution and bit stream are compatible with DVD standards. You can find out more about the patch for dvdauthor here:

FWIW, this works with recordings from the cx18 driver (for HVR-1600s), too.
