Oops. I thought you were talking about shows recorded inside MC.
If WMC saves the info in the file, and we are not getting it, I will need to revisit how these files are analyzed.
Just taking a quick look at a wtv file with the Edit DVR-MS program, the following fields are available:
WM/MediaOriginalChannel: 56
WM/MediaStationCallSign: WLVIHD
WM/MediaStationName: WLVI HDTV
Also, rather than sticking the channel number into the artist tag, wouldn't it make sense to use a new tag with an appropriate name?
