Disappointed with my HVR-2250 I started looking into tuner sensitivity. I kept seeing over and over again people raving about the ability of the OnAir GT and it's magical ability to pull in the most weakest of single and multi path correction due to the LG Gen 5 tuner.

Upon some more reading it appears that the LG tuners, at least 5th gen, used E-VSB "Enhanced VSB" http://en.wikipedia.org/wiki/E-VSB . I started searching for tuners today that use LG tuners and have ran accross two:

The new fusionhdtv cards v7 use the XC5000 ...and I found this little tidbit interesting.

I was looking at the HD-Homerun but now the fusionhdtv v7 and avermedia look interesting. Anyone know of a local merchant that carries fusionhdtv cards as I can only find them online.

My new Avermedia dual ATSC/QAM tuner uses 2 5th generation LG chips. I think it's internal name is A180 and it is also sold as the "HD Duet" I think.


For $60 with 2 digital LG 5th gen tuners, it's a great deal. The card runs very cool, too.


My original Avermedia Combo tuner (M780) also uses a 5th Gen LG chip, although it's analog mpeg2 encoder (NEC) isn't as good as the Conexant one the G2 Combo card uses from what I hear.

HDHomerun. I'll not mess with internal tuners again.

The Avermedia is A188 rather then the older PCI A180 card. Can't beat dual LG 5th Gen plus internally split coax input and PCIe for $59.99 at the "egg". I rodered 4 of them and will test them in my bad multipath environment. I have 4 FusionHDTV7 Dual Express and they are incompatible running 2 of them in a setup. Win7 MC will only use one tuner off each and show dead signal on the other two. It is definitely a driver is from Dvico because it is an older Jan08 driver and other dual cards work fine. I will test 2 of these Avermedia duets just to prove that it is a driver flaw with Dvico. I will also compare the signal strengths between Lg and Silicon Image. I am sure they will be about the same. I just want less splits in the coax line since right now I have to run the FusionHDTv7 Dual and 2 other PCIe single tuners = 4 tuners total and 3 coax splits.

Well I got my 4 Avermedia Duets A188 and immediately tried 2 of them in my main media center that previously would only support 2 of the 4 tuners from the dual Dvico FusionHDTV7 Dual Express cards. The drivers aren't native on windows 7 updates as of yet so I just ran the Windows 7 beta driver off of Avermedia's website. I am now successfully getting use of 4 out of 4 tuners with the Avermedia duets. I also noticed under the DTV signal checker that it flys through the channel signals way quicker then any other PCIe ATSC tuner I have tried. All channels are maxed out here in OKC, OK at about 7-8 miles from towers and around alot of trees using my Radio Shack VHF/UHF Boom Antenna in the attic. I have the Coax splits 4 ways with a 4 way powered splitter in the attic. The duet managed to max out the CBS signal here while the Dvico was one bar off max. It is also changes channels almost instant and faster then any other tuner including Dvico FusionHDTV7 Dual. The Avermedia is definitely the most sensitive ATSC PCIe tuner out right now and is a steal @ $60. I also noticed the LG chip number on the Duet is a newer batch then my LG 5th gen Avermedia M780 card. These might be LG 6th Gen chips because the M780 actually said LG 5th Gen on the LG chips!

yes, plus the A188's LG chips are smaller. I also saw the "5th gen" markings on the M780 but didn't see anything on the A188...so maybe they are 6th gen...who knows.


One other thing I noticed about the A188 is that the PCB is universal...they could run a hybrid, dual NTSC, or dual ATSC/QAM setup from the same PCB.


And I have also found the card works great in QAM mode out of the box in Win7.
