media center showing static only on lower channels??

[zixxer]

I bought a new pc to use as my media center computer... over the course of 4-5 days I formatted and transferred my crap over... big problem though - channels 1-~13 show tons of static. Higher channels are fine.. and a normal tv shows all channels fine with no problems.


Idea's? I have the latest hauppage drivers (it's the 500 model, with 2 tuners..) and all latest drivers in general..




(Technically this isn't software... or hardware... it's not 'off-topic either, but there's not a good place for it...)

It's not software or hardware yet it's a computer problem...hmmm.

sounds like a cable reception problem. I have two of the cards you mentioned in your post, I run a signal booster to them so I'm assured good quality, having 4 TV tuners going at once does affect quality.

yeah but when I plug a normal analog tv into the same exact coax cable going to the tuner the tv works fine...

I had a similar problem until I loaded NVidia's latest decoder and tuner drivers (I have the NVidia DualTV tuner). Problem was related to signal and noise -- there was too much noise on the non-digital stations. The driver's noise reduction filter cleared it up, though, once I configured it. Does the Hauppage have something similar?

I use the nvidia decoder.. I'll try updating that.

hmm... That seemed to help, but I still get light 'bands' of horizontal static that slowly moves down

I was able to get a pic.. it goes across the part that says 'full hour'.. The static flashes on and off going down a little bit each time..

up...

I was going to ask you if you'd tried configuring the noise filter in the decoder settings, but the only way to do that is browse into more programs and then into the NVidia DualTV settings. But if you're not using that card I'm guessing you don't have that option.

Anyway, it was the noise filter that did it for me.

Try changing your settings....could be set on "antennea" mode or whatever it's called....only looks for certain channels. Can you do a channel scan?

hmm... seems to be directly affected by which pci slot it's in (it's far worse in one slot and better in others). I suspect it's somehow intereference from my audigy sound card.. I'm going to try a different sound card and see what happens.

Okay.. I switched around pci cards until everything is on it's own irq... still getting static. I booted up my old pc and the card works fine in that.. so the tv tuner is good. Also tried switching power supplies... works fine when plugged directly into the tv (even when strung through the pc..) so it's not interference..

ugh. After all of this hassle, it turns out that the hauppage latest driver is broken. I loaded the old old 2.9 drivers off of the original cd and it works fine, but the 3.1'e' drivers caused all of the static.


what a huge waste of time. >-(
