Can anyone explain QAM (the for dummies version)?

The max number of channels depends on what the MSO in your area has built to. Most newer systems are buildt to 750 Mhz, which nets about 135 channels. Some MSO's have recently rebuilt systems with 1 Ghz plant, in which case you'll see about 160 channels. However, almost no cable STB's built can tune above 860 MHz, so channels above 860 are basically reserved for DOCSIS 3.0 equipment or telephony.

mikesm -- thanks! I just heard from Silicon Dust that the HDHomeRun can tune up to "861Mhz (ch 135)". Haupauge support claims that the 2250 can do up to 853MHz, channel 134. I haven't gotten that to work, but they're sending me new drivers; I'm keeping my fingers crossed...

Yes, even though the plant may go to 1 GHz, you are not losing anything by using these devices, since the MSO won't send video above 860.

I know the hdhomerun will work up there, since my tunes past 750.

Sigh. weeks of trying, and I'm still getting few channels on my 2250, while my HDTV gets many more. They've sent me a scanner program, and I'm trying to get them the results, but ftping the 92MB zipped file keeps dying. I guess it's time to try something else...

I think Astound doesn't send nearly as much in the clear as comcast does... They aren't deploying DTA's either.
