Summary: I have not used this a lot because I have a high definition vidio recorder with two tuners which I love but since it is no longer available I bought this card in anticipation of building a HTPC when my DVR fails. I installed the card in my PC along with the latest software from the manufacturers web site. I set it up for ATSC only and started the scan for signals. I recieved all the signals my TV and DVR pickup plus a couple more so I declare the tuners to be good.
Summary: Its only purpose for me is to record a program with a quality as if i am holding a Kleenex in front of my eyes watching TV (i can guarantee its not my rig). If the picture isnt poor enough for you, then you will diffidently be aggravated by the constant freezing as you change channels. Contacted Hauppauge several times and no response.
Summary: I installed this with an MSI 785GTM-45 mobo, in a pcie x1 slot, 4GB RAM, WinXP, and it is working; sometimes jittery or freezes. The remote control is cheap and only works some times. Documentation is almost non-existent. I have not found any for the remote with the included WIN-TV v7. Support is POOR. The software is very lame. The vendor suggests using Sage-TV instead of their software. 1-hour recording will NOT fit on a DVD; might be as big as 15 GB.
Summary: If you want to use this card to record HD content from an OTA source this is GREAT. If like a lot of people you get HD content from a cable provider this is a no go. Since most STBs do not send HD content out on the coax line and how do you combine two STBs output on 1 coax.
Pros: Dual tuners that support NTSC/ATSC/QAM with only a single connection. Dual MPEG2 Hardware accelerated controllers for SD content. All in a single PCIe card.
Summary: Locks up, recods in the wrong format - can't play back, Support doesn't reply to emails, no solutions except wait for next version (every 2 weeks!) Tells me to use Media Centre (NOT FREE!!). After 10 months of reducing the features I use and waiting for fixes, It will now cost $10 for the next version! I've HAD IT!!!!
