5V PCI only |

The answer is no. Grinding out the 3V PCI notch and plugging the PCHDTV 3000 into a modern 3V PCI slot doesn't work. It fails to power up due to a short circuit condition.
That leaves buying a dedicated computer to use as a tuner server or building a multiple tuner PCI card out of an FPGA and a bunch of tuner modules. Can't seem to find any ATSC tuner/demodulator modules available for individual orders. Are these banned from individual sale by the MPAA or something? |

It was totally inexcuseble what pcHDTV did with this card. Come on, who now a days designs a card for 5v only? What is this 1999?
I just bought a http://www1.us.dell.com/content/products/productdetails.aspx/pedge_sc1420?c=us&cs=04&l=en&s=bsd just to find out I cannot plug my pair of pcHDTV cards in there. Errrrrr. 
It did not even occur to me to check for that before ordering. I routinely tell people that you only have to worry about the 5v issue "with old crap". Most of the newer stuff is universal.
Now I have to buy another vendor's ATSC capture card. I could not help but notice that all other competitor's cards are dual 5v/3.3v design. Even the ones based on the same chipset. pcHDTV needs better engineers.

There's no accounting for idiots who don't bother to find out the specifications of a product before they buy it.
I bet if you spent more time reading and less time whining, you'd get a lot more compatible products delivered to your doorstep.
Grinding the notch, sheesh.
Someone oughta grind your head because it sure aint sharp enough.

There is a reason annomous posters are called "Annonomous Cowards". Coward being the operative word. "There's no accounting for idiots", I agree, that is why they log on as guests.
Because all they can do is flame.
If they would have bothered to lookup PCI specs from http://www.pcisig.com/specifications/conventional/ they would have discovered that 5v is not even supported anymore (in the latest pci spec). All cards designed after 2001 should have been universal. Try reading their FAQ and downloading their checklist.
The conexant chipset used in the card supports both 3.3v and 5v.
There are at least 3 other vendors that produce hdtv capture card using the same chipset. They all designed their cards to be universal.
Thats why specs exist, so the stuff will "just work". We routinely connect devices based on standards such as usb, sata, and yes, pci.
Vendors are supposed to follow the latest published specs when they design their products. I was upset because pcHDTV did not follow the spec.
A PCI card should follow the PCI specs. What a concept.

Oh wait, did you say *most*. You imply *all* in the rest of your post(s).

If you would care to research this I would like to know your results. The only truly competing product that I know of is the Air2PC card -- and from the picture it appears to be a 5V only card. Is there another PCI HD tuner card that work with linux? |

Try reading <latest linux kernel>/drivers/media/video/cx88/cx88-cards.c. There are 27 pci cards supported by the cx2388x chipset alone (the same chipset family used by pcHDTV 3000). BTW, Conexant cx2388x is not the only chipset supported by Linux.
There are some models that are not sold any more. Some of the cards are not sold in the US. Not all of them can do both OTA and QAM.
There are some newer models (like Fusion HDTV5) that are not listed there but will be in the dvb cvs soon.
There are plenty of vendors making linux compatible HDTV cards. I don't want to start listing pcHDTV's competitors on their forum. However, if someone wants to find out what other vendors make linux compatible HDTV cards. It is trully a trivial task (for anyone who is competent enough to use google).

| I agree that making a card 5v only is idiotic. Anonymous posting shouldn't be allowed either. Probably someone from pchdtv posting nonsense as usual. Very poor engineering AND documentation. |

So I as a technician could bypass the 5v-3.3v regulater if there is one on the card? but then the slot keys would have to be addresed I guess sigh..anyone want 6 pchdtv cards?
