Some people are claiming that the HD2000 or HD3000 could support QAM demodulation. Knowing which chip is on the HD3000, would be easy to see if it "could" support it.

OR51122 Supports 8-VSB and NTSC
OR51132 Supports 8-VSB, QAM and NTSC

It's clear that if the HD3000 uses OR51122, it won't support QAM.

There is a FAQ circulating that says that both HD2000 and HD3000 could support QAM, but no information about which chip the board has.

It's not that it makes any difference (I ordered one) but the unofficial FAQ info could be misleading.

"pcHDTV has the micro code that is used for decode cable signals. This is what prevented the HD-2000 from allowing users to watch HD cable - the HD-2000 card does support QAM, but pcHDTV was not able to get the micro code"
- If they have the microcode for cable, why does it prevent to support it? I might just understand this wrong.

Maybe somebody can lighten the subject.

I have two HD-3000 cards and just checked one of them. It has an OR51132 on it.

Thanks, now it's clear Smile Could be supported. But since the Terestrial spectrum is almost the same (probably the same) as cable, it would be possible.
