EyeTV Radio recordings no longer play on iTunes
I have recently updated my EyeTV software on an iMac running the latest version of Lion. Until recently (after the update - to 3.1.1, I think), I could export Eyetv radio recordings to iPod format and they would automatically be placed in iTunes and could be played. Now, exported files are still created (allegedly M4A format) but they will not play on iTunes. I am not sure if this is an Elgato Eyetv or an iTunes problem. The files will play on VLC so the files have real data in them. I would be grateful for any advice.
iPhone 4, iOS 5.1.1
