Thanks for the method.

However guide still displays no data for these newly added channels. Is there any way to get the guide to display programming lineup for the new channels?

thanks.

I have two Hauppauge WinTV HVR-2250 dual QAM cards installed for 4 QAM and 4 NTSC tuners on two cards.

I was disappointed that it found NONE of the digital QAM channels automatically. I had to manually add each of the frequencies by looking at the channels found by my Sony KDL-52XBR2 TV.

One thing that REALLY annoys me:
The QAM tuner in my Sony TV somehow finds the local ABC affiliate (WSBTV) on channel 0. The LG and Samsung TVs at work (same cable provider) can’t find ch 0 in a scan, and refuse to switch manually to ch 0. Likewise, 7MC will not allow me to manually add Ch0. The “Next” button will not enable unless I type in some number other than 0. Ugh!

I selected the option on my TV to display tuner diagnostic details while I was tuned to that channel. It seems to indicate that the channel uses QAM256 modulation.

When I added all of the other channels to 7MC, I used QAM64 and they all worked. If this one uses QAM256, it’s the only one that does.

Even so, 7MC won’t let me specify the modulation type until after I type in the frequency, and it WILL NOT accept a frequncy of “0″.

I don’t know if QAM on Ch 0 violates some spec. I would assume so because my Sony TV is the only one out of 4 QAM-capable devices I’ve tried that can do it.

I don’t know if I’m dealing with a hardware, firmware, driver, or 7MC GUI limitation.

I emailed the lead cable engineer a few days ago (I work on the Internet side of the same local cable company) and he hasn’t responded to me yet.

Is there a batch way to correct ClearQAM channel guide data? I find going through the menus over and over for 100+ channels is tedious. I guess having over 100 clearQAM channels is a blessing. Perhaps knowing which files and the format of those files would be enough for me to hack something together in perl?

Fantastic website. Wish I found this a few weeks ago.

Thanks in advance.

Has anybody been able to get WMC to recognize a Dvico Fusion 5 USB as a clearqam capable tuner? I have the latest drivers from Dvico and I am able to tune in clearqam channels using the Dvico software, but can’t with mediacenter. I’m using Win7 Ultimate x64 RTM.

Question if anyone has any ideas. I’m using 2250 with win7 RC. It finds 5 DT channels but I don’t get any of the HD channels and the 5 channels I do get are not correct. What I mean is that 5.1 should be our local CBS HD feed but instead I see what’s on 17.2 the NBC #2. Anyone have a suggestion?

I just purchased a Hauppauge HVR-1600 and followed the steps in this guide, including the registry hack. The randomly numbered channels show up in the edit list, but I can’t watch the ClearQAM or the analog cable channels when connected to the ATSC/ClearQAM input. The analog channels work fine in the cable input though.

I even checked out Shaun’s other forum post, but the analog cable channels still won’t show up.

As long as you’ve got a ClearQAM capable tuner in your machine, yes. I personally use a Hauppauge 2250 and an AverMedia Duet that perform beautifully with ClearQAM.

Noobie question… so does the ClearQAM capability in Windows 7 mean I can get rid of my HDHomeRun and just directly plug the cable coax into the tuners on my PC?

Thanks,

I am having some problems after upgrading from Beta to RC. I posted on the Green Button forums here:

http://thegreenbutton.com/forums/372714/ShowThread.aspx#372714

Any help from here would be appreciated.

More details in the post, but here is a summary of the problems:

Problem 1)

The automatic setup doesn’t find my standard cable channels. I can manually add the Qam channels in, but why doesn’t it find the regular cable channels?

Problem 2)
When I set up the guide listing for the newly added Qam channels, the listings are 3 hours off (but computer clock is fine).

Thanks a bunch.

Thanks for the reply – the issue is that RC1 will not allow me to choose the digital listings (with all the channels I need) and only automatically chooses the analog one (with 60 or so channels). This does work with Vista, but RC1 won’t let me choose digital listings.
