I copy my p2 card files to an external HD so I can re-use my cards. Lately, when I link to AMA volume on my Avid NC 10.5, some of the clips freeze while playing. Not all the clips, just some. Audio is fine. I've tried re-copying them to no avail. I am forced to pull the individual MXF files and run them through Adobe media encoder. This is a recent development and as you can imagine, it's horribly time-consuming and it's getting worse. Between me and my engineer, we've tried all kinds of things. Has anyone else run into this? Does anyone have a suggestion? Really need some help here. Thanks.
