There is also the issue of time and processing required to transcode the
files to a format other than the one that it was recorded in originally.
I like the two types of discs but I would think of them as primarily
based on the input source used to record them.  So if the file is a
*DVD* encoded MPEG2 then by all means use standard DVD format but if the
files are anything else provied an option to transcode it to a DVD
compatible format or record as files that you would play back through
myth only.  Because most of the time waiting the MANY hours that would
be required to transcode from MPEG4 to MPEG2 isn't going to be what I am
looking for.  The other options are SVCD and friends and I think they
make good options once again IF the file is already in a compatible
format but I have to wait about 8 hours for nuvexport on my Athlon 2400+
for a one hour show to go from MPEG4 to SVCD.  At that rate it will take
a long to archive very much stuff.

Add my vote too as someone who would love to see this done.
