I think I know what's going on here. There actually *are* some additional bits in the raw data stream returned by cdrdao that can be used to detect, and in some cases correct, certain kinds of errors in the CDG channels. But cdgtools doesn't know about these extra bits, and doesn't use them to perform any error correction. Standalone players do, though, so when you write the same bitstream out to a new disk, the standalone player can correct some of the errors. I haven't found any documentation on the proper interpretation of these error-checking bits, but I have found a software program that can interpret these extra bits correctly, and it generally makes a cleaner rip than cdgtools, even on the same hardware. Unfortunately, it's a closed-source, commercial, Windows-only program.
