In North America, my experience is that it's almost always edge track.  Once
in a blue moon we'd get center track or even stereo.  Chace Productions and
some other firms specializing in optical sound transfers often would produce
stereo or dual-mono mags with signals on both tracks, but the mags were
always labeled "EBU 2-track."  Sometimes, those sound transfers were
Dolby-encoded as well, but I think that practice has gone by the wayside;
now, I think they're delivering DATs or DA-88s.

In Europe, I'd say anything goes.  You'd think that center track would
theoretically sound better, since it's further in from the edge of the film,
and less susceptible to dropouts.  Probably the best bet is to use a 2-track
head, and listen to both channels, if the mag is not identified.
