A quick look through my library of downloaded signals shows most VCRs using RC-5 use the same set of signals and device number 5. I also have samples of those same signals using device number 6.

Both the common (5) and the rare (6) signals are together in this CCF file:

The common ones are his Philips VR960 and the rare ones the VR723, but I suspect the VCR is configurable, so it isn't the model number that makes his VR723 use the less common codes.
