I have a Samsung Series 6 with built in HD tuner and a Mediaportal based HTPC with an Hauppauge HVR3000 and a PVR150.

I was in Lyall Bay where I got great coverage and the TV and HTPC both worked perfectly with DVB-T. I setup the aerial and cabling and tested it on the TV then moved it to the HVR3000 in Mediaportal where it worked perfectly.

I also had a Sky SD feed into the PVR150 which also worked perfectly.

I have just moved to Island Bay on the west side and took my aerial and TV and HTPC with me. I mounted the aerial and aligned it as per the neighbours and connceted it to the TV and it worked perfectly.

I then decided that I wouldn't get Sky and would chuck another DVB-T card into the HTPC. Picked up another HVR3000 card and installed it. Updated drivers to the latest version, bought a splitter from Dick Smiths and some patch leads and connected it all up.

Scanning for channels gave me no signal on both cards yet I could plug one of the DVB-T leads into the TV and get perfect reception straight away.

I tried removing the splitter and all possible combinations, leads etc and have no luck with single card, direct connection etc etc. The best I got was with a homemade lead I can get four channels on one of the cards.

The aerial is a large top of the line from Dick Smith, all cabling and connections are crimped and sealed and worked fine in Lyall Bay and provides perfect reception on the TV built in tuner, yet the HVR cards have issues with reception.

Is it possible to have too much gain? All the aerials around me are quite small in comparison to mine. Getting some channels on one of the cards was only possible when I used a low quality home made lead thereby incuring some loss I would have thought.

Anyone have any thoughts?

Cheers
Matt.
