I have seen some that have only one format on the disc, yet require dual
layering to fit it all on the disc. These discs probably would cause
some quality loss when copied to a single layer disc with lower capacity.

With variable bit rate encoding you would be hard pressed to see the
difference.

All DVD's are variable bit rate, so what was your point again?

Unless you system is absolutely garbage, perhaps a window on a computer monitor
or a 13" tv, halving the bitrate will most defineately produce a rather
noticeable difference.

That depends on how you compress it. Using MPEG-4 instead of MPEG-2
you can easily halve the bitrate with no noticeable loss of quality.
