RE: [Avid-L2] DNX 220X HD and ADRENALINE

Hi Chris,

Adrenaline should not have any problem playing back the DNxHD 200X you digitized. The codec change in 4.0 should not affect any hardware playback (and there were no changes from 3.x to 3.5.4 to cause this problem). However, the CRC error you are getting may very well point to some kind of storage corruption. Each frame digitized by hardware contains a CRC and during playback on hardware that CRC is recalculated and compared to what is stored in the frame and if they don't match you'll get this error.

Maybe I missed something along the way but I was pretty shocked to find out that our 3.X Adrenaline HD could not play DNX220 X out to tape via digital cut. Even a crash record gave our Panasonic 1400 fits. The Adrenaline did somehow digitize this material.

So thought I would move the project over to our Symphony Nitris DX 3.5
Getting an error on playback. "Codec fatal decode MSG: Card2:Decode: Pipe 2CRC error" One of those errors over a black program monitor screen.

Wondering what is going on. I know there was a slight change to the DNX codecs from 3.x to 3.5.x. But I thought they would at least be forwards compatible .
