I've experienced and read about this before and "assume" someone's doing something about it (?), but it is ironic that the two processes of copying the BPAV Folder and then "rewrapping" to MXF take something very close to or even longer than realtime, negating one of the big advantages of this tapeless society we're "enjoying".
The aspect I was wondering about is this so-called "rewrapping" - if there's no re-compressing going on - what the hell is taking all that time?
Information and/or theories welcome.
