[Avid-L2] Multi-Cam freezing

DVCPRO HD at 720p requires less horsepower than 7 streams of 1080i @ DNX
175. The DVCPRO HD codec is also thin raster..only 960 x 720.

Still, the OP did manage to get it to work for awhile. With a single
drive, you can have some variation in read/write speed, depending on where
the files are physically written on the drive. Or you might just get
lucky. But overall, the math doesn't work.

Really, if you want to do this effectively, without hiccups, in HD, you
should think about setting up 2-3 internal drives in RAID 0, if you can't
afford a full blown external RAID.

trying out 7 streams of DVCProHD 720p60 (plus two PCM audio streams) and it
is working fine so far on an internal eSata drive in my old 2006 Mac Pro
(v1.1).
