I searched the forums and I couldn't find an answer, so here goes. I was recording 720pn /24p on a shoot last week. I removed a full 8 Gb P2 card from the camera while still rolling, the camera was recording on the other card now (16Gb). I tried to put an empty 8 Gb card back into slot 1 on the camera and the screen went off and in red letters a message was shown to TURN OFF POWER. As far as I can tell, no clips were affected in a negative way. Has anyone seen this ? If so any remedies ? All other footage is fine, but the HVX did do this a few times. One time the 16 Gb card said it was full, but when I went to dump the footage, it said that only 10 Gb had been used. That only occurred once, every other time it said that 14 + Gb of space had been used. Thanks as always for your insights.
