All 3 of the USB tuners I have, come with external rf inputs. Otherwise I wouldn't even have them.
I was under the impression you were able to get your 950Q working.
On a side note, though Hauppauge makes no mention of it on their product pages,
using TSReader, I just confirmed the Hauppauge Aero M can do Clear QAM (tested in XP only).

Of the devices i have, driver support can be summarised like this:

Device     Linux    XP       WIN7   QAM enabled   Comp ANA In
inDtube     Y       Y         Y         N             Y
Aero M      Y       Y         Y         Y             N
ATI650 USB  N       Y         N         Y             Y

Majortom,

Thanks for the clarifications.


Yes, my 950Q and WINTV v7 now functions correctly (since I did Windows repair Install),

HOWEVER,

Jacks SmartDVB (latest) sent to me as a package does not always work with the 950Q (v7 drivers), it worked one time then not anymore, and cant get signal level bar.

[majortom]

not certain i'd get too hung up on the signal bar at this point. first priority should be stabilising it. The Hauppauge Aero M indicates zero "Signal Level" as well in Smartdvb. Its the quality indicator that matters.

From my testing, with TSReader's ATSC.dlls (we can play with TSReader's ATSC Source DLLs since we have the source code). The information reported by the frontend hardware in two of three tuners here is useless in terms of "Signal Level" anyhow.

I'm sure he'll get around to fixing up the aesthetics sooner or later.
Still working with him to try and get Clear QAM working in SmartDVB.

[balm]

agreed,

at least I know it can work with latest drivers, just not sure yet why its so unstable....guess more log files will help...

thanks

For what this is worth, I had a hard drive slowly go belly up.... In the process, it corrupted the WinTV7 channel database.

Result: Win7 would start, then quickly exit on it's own, no error reporting.

If I then load the channel recording program viewer / editor, it would show as normal minus the grid lines. Nothing else could be done with it.

I was able to do a complete drive image before the whole shebang went west.

A re-image onto a new drive worked flawlessly, including bringing back the corrupted WinTV7 install. :-)

Re-did the install from the web download of WinTV7... When it found the previous channel database, I told it to NOT use it, but create a new channel database, and all worked perfectly.

This may not be your problem, but corruption of various elements of the WinTV7 install do seem to upset it quite easily.

One oddity, the "Open Scheduler (only)" icon *ALWAYS" leaves it on screen, but not having focus. The "Open Recordings (only)" icon works correctly. Strange....

BTW, this is all on Win7, x64 platform using WinTV7 with a 950Q

Does viewing ota television on a laptop using a usb tuner use internet bandwidth ?

[j0dest3r]

Nope not at all, only a bit for the guide data every once in a while, but that's it.

^^^It can sometimes get guide data from the OTA broadcast so that isn't even necessary, unless your software insists on it.
