I bought a Monoprice ATSC tuner for $30 to use in Quebec City (ste foy) this summer, but in the OTA reception forum I asked and Global and CBC were both analog. I thought the ATSC would be backward compatible with NTSC/analog, and I just tried it in my laptop and it couldn't pick up either of the two (weak signal) analog channels here. Does this mean it's not? :confused:

Edit: Link got censored? but here's the description for what it's worth:

Not backwards compatible.
You needed an NSTC/ATSC tuner in this case.

If the box doesn't say NTSC it is not analog capable.

You'll have to wait a few years to reap the rewards of your purchase.

Do you know of any good ones?

Well, the entire HTPC forum has threads devoted to the topic, so this is the one you want:

USB2.0 Digital TV Tuners (http://www.digitalhome.ca/forum/showthread.php?t=49381)

I went for a $20 one on Dealextreme, if it works that's good enough... I can always get a better antenna to plug into it anyway and it won't work anymore after the transition to digital so $20 for a temporary TV solution doesn't seem too bad. Picked up a FM transmitter for the car as well ;)

I have the Hauppauge HVR-950Q USB stick. It supports ATSC/NTSC and even QAM. I really like it. I have not watched much NTSC stuff with it but it does work. It supports Windows 7MC natively and is basically plug and play under Windows 7.
