One factor which militates against this method is that DiscWelder will not
allow a no-pause situation between tracks when you record mono this way.
Since I record a lot of classical music, which, in most cases, calls for no
pause at all between movements of a symphony (normally you want at least
hall ambience in a live recording to remain constant between movements), I
found this extremely annoying, and contacted DiscWelder to find out why it
was happening. The response: monophonic recording in the center channel, in
the absence of left and right data, is non-standard for a DVD-A, and hence
the no-pause-between-tracks feature is disabled. You could record in either
the left or right front channel, but then you wouldn't have the automatic
routing of audio to both left and right channels during playback. Hence, it
seems that the only way to achieve pain-free monophonic listening with the
possibility of zero-time pauses between tracks is to record dual-mono, i.e.
the same thing in both the left and right channels. On the positive side, it
still allows you to pack a lot of stuff onto a single disc. If the no-pause
situation is of no consequence to you, then by all means use Tom's
