hauppauge 2250 with Windows Media Center

I started having trouble with this a couple of weeks ago.
I worked with hauppauge support and got their WinTV product installed and working, but I really don't like this app.  I'd prefer to use WMC, however it fails to find the same channels.  In fact, it only appears to find the pbs channels.  I've tried reinstalling wmc, but it still isn't working.  A signal scan shows all channels as weak, except for about 2.
Any ideas as to why I'm able to get this working in WinTV, but not WMC?

Unfortunately signal level issues can be VERY difficult to diagnose without very expensive test gear.    Are the unused outlets from the 4-way amp terminated?    Some amps can be very sensitive to unterminated outlets.    You indicated you "... have had one additional connected ..." ==>  any chance your problems started when you no longer had this connected?  (if so, then simply terminating that outlet may help).

Another possibility is that the 4-way amp is no longer receiving power.

Clearly SOMETHING changed a couple weeks ago ["... I started having trouble with this a couple of weeks ago."].    Think very carefully about what that might have been.    Any chance your antenna was rotated some by a storm or winds?    Ditto the connections (as I mentioned earlier) ... including the connection of the cable that goes to the antenna on the pole.

I don't know what your physical setup is ... i.e. how feasible it might be to do this ... but if it's not too difficult to move, it would be very instructive if you could take your system to a friend's with cable and see if all works well with a known-good cable signal.     That would at least let you isolate for sure whether or not this is a 2250 problem or an external signal quality issue.
Hi sirbounty how are you,
it really concerns me to to see you write that you tried to uninstall/reinstall WMC, you can't it is part of the OS.
You're on windows 7 right?
Since the TV card is weak and not functioning right then we need to check drivers and settings and possibly antenna.
Is the settings analog as analog TV is gone only Digital now in most regions in the world.
You may need to set the analog and the digital.
As you said yourself here is your problem
A signal scan shows all channels as weak, except for about 2.
Ok I don't know what all steps you have taken so here we go from the top/

I've found that Windows Media Center is more "picky" about signal strength than some other apps; but works fine if it's got a strong enough signal.

Do you have a distribution amp on your cable signal before it's split to the various devices (e.g. your 2250)?    I use a distribution amp in the attic to ensure a strong signal at every outlet; and then a unity-gain amp at my HTPC which drives 4 2250's (8 tuners total).    This works perfectly with Windows 7 Media Center  [Using Tuner Salad to eliminate Media Center's 4 tuner limit].

Other possibilities ...

=>  Your cable connection is loose at some point (check all connections).
=>  The 2250 is in fact defective (do you have more than one?   ... that certainly helps with isolating this kind of issue)
=>  If you DO have an amp, perhaps the power adapter for a power-over-coax feed to the amp has been unplugged.    Be sure to check for this (it should be near one of the cable outlets in your house).

Merete - it is most certainly possible to remove WMC...it's under windows features and all you need do is uncheck it to remove it.

garycase, I thought perhaps you might be on to something and it did appear that I had my amplifier cabled wrong.  I also have two outlets there, one controlled by a switch for the light - had to make sure it was in the correct outlet.  I've adjusted all of that, but it doesn't seem to have helped.  I wonder if perhaps that is starting to fail, or how to narrow this down...  I only have one 2250, but this has been working fine up until a couple of weeks ago.  I've done a fair amount of troubleshooting to try to identify the problem, but suspect it's hardware failure occurring at some point.  Yet, support states I wouldn't get any signal if the card was failing.  And considering I can get more (though still not all of the channels I used to) via WinTV, I don't know that it is the tuner card.

I only use an external antenna - I think it has some sort of amp on the pole, and then that cable connects to a 4-way amp under the house, which only goes to this computer and one unused outlet (though I have had one additional connected to the l/r tv, which was receiving several more channels as well).

When I perform a signal scan in WMC, sometimes I get that it was unable to find a tuner with a signal, sometimes it only returns one found with a 'more details' indicating that the other wasn't receiving a signal, and just now it states 'tuner unavailable, restart the computer and try again'...  I'm really leaning towards a failing card, but I hate to drop another $100 on a card and that not be the issue.  Their own support assures me that if WinTV is working (which is probably still only about 75% of the channels I was getting), then the card is fine...I'm just not convinced.

Well, I snagged an old desktop antenna, plugged that in and it found both tuners.
It was briefly picking up one of the main channels I was after, but now it's stating there is no signal detected for that channel... Still feels like the card is failing/quirky to me...
sirbountyAuthor Commented:
Are the unused outlets from the 4-way amp terminated?

Terminated?  You mean like installing some sort of coax cap?  Not sure I follow, but I've never used all 4 of them.

Unfortunately I can't think of anything that changed.  It all started when I got that 'no signal' icon in my tray when a scheduled recording was missed.  We did have some high winds that week, but I don't see that the antenna moved.  However, I did go up and adjust it a bit, lost all signals, so returned to the original direction.

I'll keep trying some things here - maybe I can grab another amplifier...this desktop antenna is likely not very powerful at all.
Gary CaseRetiredCommented:
I agree that card sounds like a likely culprit.    If you're fairly confident that your signal hasn't changed (antenna hasn't rotated; amps have power; cable hasn't become loose), then that's even more likely.     I've had a 2250 fail on me in the past, but it was fairly easy to diagnose, since I have 4 or them :-)     Nothing like a spare part to help with this.

Ok, I guess I'll keep an eye out on ebay ;)
Thanks for the help.

"... Terminated?  You mean like installing some sort of coax cap? "  ==>  Yes.   Something like these:  http://www.digikey.com/product-detail/en/25-7100/367-1201-ND/3837646?WT.mc_id=IQ_7595_G_pla3837646&wt.srch=1&wt.medium=cpc

A local electronics shop should have them for < $1 each; or you can buy a 10-pack from Amazon:  http://www.amazon.com/Type-75-Ohm-Terminator-Pack/dp/B000AAN76Y

If you haven't used them in the past, your amp is probably okay without them.   I always terminate all unused outlets, however ... it ensures there are no impedance issues with the amplification circuitry.
