are 120-minute mini-dv tapes available?

[Malcolm Hamilton]

Hi everyone -
I've got to transfer 175 (approx.) Hi-8 tapes to mini-dv (archiving 
my family movies).  It'll be a tedious project regardless, but it 
would sure make life easier if my Hi-8 tapes and mini-dv tapes were 
of equal length.
As it is, most of my Hi-8 tapes are 120 minutes long.  And as far as 
I know, the only mini-dv tapes I can get are just 60 minutes (best 
quality).  This means I'm going to have to time everything, and make 
sure I'm at my desk at the 60-minute point.  And check, and rewind, 
etc., etc.

Does anyone know if 120-minute mini-dv tapes are available somewhere, 
or if they're on the horizon?

By the way - I can get Maxell mini-dv tapes at a good price compared 
to Sony's.  Are they as good?  (I'll just be recording on these tapes 
once)
Cheers,
Malcolm
