Some DVD players used to be a bit picky about Tivo's normal horizontal resolution (540?) not being one of the official DVD horizontal resolutions. It is quite some time since I was fiddling with all that so don't know if that is still an issue.
Yes of course, if you were to use that non-standard resolution it wouldn't be a pukka DVD. Unhacked tivo:
Best=mode4, 544x576
High=mode2, 480x576
Medium and Basic = mode1, 352x576
So only Medium and Basic are valid DVD resolutions.
The mode 0 hack (replacing the fpga7114.o file so that the PAL settings for mode0 weren't way off screen, and it was useable) enables you to use mode 0, 720x576, which most people then set for Best and High.
A mode 0 recording run through the tytool process end-to-end provides the highest possible video and audio quality. On my setup it's better than watching on the tivo, since the tivo video circuitry introduces noise, which my dvd player doesn't. And for those unlucky enough to have white flashes on their mode0 output, the flashes aren't in the recording or on the DVD.
