WGBH is on QAM! For those that were unaware, I just bought a Slingbox and used a Coax connection (in addition to Roku and Tivo)...and realized that QAM has 2.1 WGBH PBS which is not on the MC system on it's own.
also 13.2 THE COOL TV is on QAM and it's all videos...very cool channel.
It's too bad Metrocast doesn't put them on the system build.
One last thing, if you want FOX in HD you have to go to 25.1, even though Fox is actually on 6. 6.2 gives you WCSH Weather plus or something goofy.
