I can confirm I get working ATSC video capture (with a selectable
channel via frequency) using Máté's patches, and it does patch
successfully against git master. (If I rename the pins from "003" to
"3" and "001" to "1" that is).
There are a few minor issues that we will try and address before
commiting it, I think, like submitting changes upstream to mingw-w64,
making sure license is OK, adding options for subchannel for ATSC,
etc.  Probably offline.

Thanks to Máté for his work on this.
