Since updating to 215 some three weeks ago, I have had a couple of recording anomalies.
A (timer) recording appears to have succeeded, but trying to play it brings up the dreaded "Unrecognised media format" or some such when trying to play it from the "Recording" folder.
Anyhow, copying the file off to a PC via WizFX and processing with VideoRedo yields a good, playable version after conversion to .mpg
I don't recall this happening in the past on .197 in the 4+ months I have had the BW.
