I resorted to capturing to cineform intermediate to get around the building peaks issue, but I would rather have a 12gb m2t than a 40gb intermediate for one pass edits.
Problem is on 2 separate systems I have gotten 1 BSOD, several lockups and exception errors. I am also getting sporadic single black frames, which I thought was an issue with V6 when you had preview ram set to something other than default. I have had more crashes in 1 day than I have had in V6 for a year on over 40 long form projects.... My excitement about the great m2t performance is waning.. :-(
