Need Help, found then lost QAM channels, cannot pull straight video signal via card (1 Viewer)

[RGPFX]

Well the weird thing is that a week ago, before I twiddled something unidentified in the software interface, I did get about 2 dozen QAM HD channels.

The Live feed thing is good, although the aspect ratio is off.

The box is far enough from the PC right now that running any cables other than coax across the room and over and around a door is impractical. The cable box does also have a composite set of output and HDMI.

The PC card is Hauppauge WinTV HVR 1255 model 22XX hybrid ATSC/QAM I cannot find a pic, even on Hauppauge's site

You can always try some of the other frame size options in that settings section:

OK. I'll try the other settings.

The cable box was not off when I was receiving the QAM channels. Is there a specific channel that is better for carrying the QAM?

Another question: The MP docs refer to an editing module as one of the extensions, but I cannot find that module. Has it been removed? If so, is there another software you could recommend? My ultimate goal is to edit shows and burn to disc, either DVD or BD for final storage.

Okay. Well then I have no idea what is going on... but like I say, in my experience the QAM channels would not be mixed/underlaid/overlaid with the output from the cable box on an RF out. RF pass-through (loop out) yes... but not RF out.

Is there a specific channel that is better for carrying the QAM?

To receive the QAM channels requires an RF/coax feed from the cable provider. It is not possible to receive them any other way. The trick for you is to find a way to split the coax from the cable provider to enable you to hookup both the cable box and the PC. Otherwise you have to find a way to loop the signal through the cable box. That requires knowledge about the cable box functions (ie. the cable box manual would be helpful).

There is no editing module. If there was one in the past then I certainly was not aware of it. You'll need to look at other options here.

My cable box is ATT u-Verse so the data feed going into the cable box is a CAT Ethernet cable. No way to get a video feed from it, I don't think.

Heh, goes to show how much I know about US cable boxes!
Sorry, I think I'm out of my depth at this point. Like I said, if you can point me to the manual or something I might be able to figure it out. The other alternative is to call AT&T... though I guess what you're intending to do is something they're frown on, so you'd need to choose how you phrased your questions really carefully.

I did a little web/groping on ATT u-Verse TV and I'm not sure how a ATSC/QAM tuner could find channels. According to ATT/wiki u-Verse is really based on IPTV. It looks like the "ATT box" has a coax analog Channel 3 output option for older legacy TVs. Not sure if there is a clean MePo connection for u-Verse

if you look at the bottom of this page for links to a few TV setup options, there is a link to the "AT&T U-verse Receiver Installation Manual"

I'm not sure what happened, but the first time I tried to scan channels (lulled by the blissful ignorance that it was apparently impossible) I got a score or more of channels. I was definitely watching FOX in HD. I flipped through a few others, but they were definitely there. Then I tried some other settings to try to get the live feed, because I really want to record my DVR'ed stuff and then the channels were blank. The key thing is that at one point, they were there!?!

I tried uninstalling completely with FULL option on and reinstalling, but it didn't help and it kept the live feed channel and hybrid configs I set up as per the posts above. There must be registry keys that The full install does not remove that hold that data. Maybe if I can flush those too and reinstall fully again, the magic will return.

Ideas? I really liked having HD coming in to my computer.

Is it possible it was pulling them from the air without an antennae, maybe using the coax as an antennae? Just thinking out loud here . . .

Nor am I now...

The channel details are stored in the TV Server database. To remove them, uninstall the database (ie. in your case, uninstall MySQL).

Now that you mention it... I guess that is a reasonable possibility. I can't tell 100% for sure as only partial logs are available from those scans, but based on the fact that (1) we can't figure out how your U-verse box would have passed cable channels and (2) that most of the channels you found had real names... this is the only reasonable explanation I can come to.

So, maybe try this...
1. Open TV Server configuration.
2. Go to the scan page for your digital (ATSC) tuner.
3. Untick the "tune QAM instead of ATSC" option. This should disable the frequency plan (QAM Standard, QAM HRC etc.) selection field.
4. Scan and see what happens.

Well, I unplugged the coax at the cable box side and ran the ATSC scan and I got my channels. Mystery solved.

Thank you for all the help so far.

Any more info on correcting the aspect ratio on the line-in feed?

Also, the quality on the line-in feed appearing in my monitor is not as good as on the TV screen. For example, on news channels, the Chyron letters and text in the lower third appears clear and in white on the tv, but with chroma flashing and blur in the computer window.
