The ATSC support has been tested. Haven’t had a chance to burn in the ClearQAM support. And there’s a bunch of cleanup work required before it can be submitted upstream. But it does work, and should satisfy those who have this board and want to see it working under Linux.
Thanks go out to Trident Microsystems for finally allowing this release, as well as to Hauppauge and PCTV Systems for pushing them on it for so long.
Testing/feedback welcome of course in the comments below.
