Keep Bugging Avid !

While I do not have any actual knowledge of their code, I strongly feel that this is a very easy fix for them.
In Avid, it appears that they have a memory buffer to hold a "Group of Pictures". This buffer is larger enough to hold the entire GOP, but only if the bit-rate is 50 Mbps or slower.
Above 50 Mbps, the total size of the GOP is larger than their currently allocated memory buffer.
Thus, when one uses any of our bit-rates higher than 50 Mbps, the entire GOP is not contained in the buffer. This upsets the Avid program, as it was expected to be able to go back to the first frame or any frame in the current GOP. Thus, the Avid error message.
It could be as simple as Avid recompliing their program after increasing the size of the GOP memory buffer.
Or it could be a major hurdle if they can not increase the size of the memory buffer for some technical reason.
In any case, we will be very happy when Avid addresses this issue.

...Hi Dan: You are quite correct. I don't know if there's anything you can do from the CD corporate end of things, but if there is I hope you folks at CD will keep pressing them about this. Avid is notoriously slow to adapt, and they only seem to move when pushed by enough people.
