Im looking for a x64 or Windows Vista compatible driver for an Asus NTSC
TV-Tuner card (Conexant Falcon II shipset). Asus drivers download website
doesnt have any x64 drivers, and Conexant doesnt even have a support website
for their Tv-tuner card shipsets.

Any help or suggestion will be appreciatted.

This card is actually a part used in HP Media Center PCs. My card has HP PN 5188-4124. My copy of 32 bit Windows 7 Beta 7077 had a built-in driver. The problem withmy card is a mysterious front panel connector that seems to handle the audio output. I am going to have to hack something to get audio to my MB sound input.

This my 4th TV tuner card. All the others had a 2-ch mini-jack audio output. A jumper cable was used to connect to the sound card or MB Aux input. The Falcon II only has inputs on the bulkhead. The outputs, I believe, are located on the inboard end on a 10 pin inline connector marked PANEL 1. The card has beautiful video quality with the Windows 7 driver. I just need to adapt the mysterious connector. It also has a hardware MPEG2 processor which is a requirement for its intended use as the key component in a Linux DVR using the freeware MYTH application.

If using audio input from a STB in conjunction with an S-video input on an
NTSC/video capture tuner card the audio has to come into the tuner card and
not into the MOBO to insure that the sound is not out of sync.
Tuner cards do not normally have either video or audio output connectors,
their outputs are passed to a PC application program through the cards
driver interface.

Obviously I am not familiar with you card. Do you have a link to its specs,
user guide?
Here are some thoughts.
The 10 pin connector may be for test connector setup used during the
manufacturing process.
Audio output from the card would only be available from normal tuner RF
input content and not from an MPEG2 encoded data stream.

When watching TV in Windows7 what if any sound is available from your normal
MOBO sound Line or Speaker out connections?

I tried the ASUS Falcon II TV card again in the new PC I built about 6 months ago. Windows 7 may have matured with the Build 7077.
Drivers were downloaded automatically and the following devices appeared with no errors or exceptions:
Conexant Falcon II NTSC Video Capture
High Definition Audio Device
High Definition Audio Device
There is no need for TV sound connections as that is handled by Direct X.
Windows Media Center seamlessly configured the TV functions better than any other TV app I have ever used. I have experienced quite a few and most had serious problems. Windows 7 MC makes the TV card very user friendly, especially handling scheduled recordings.
I still have not decoded how to get the FM radio function working.
Not bad for a card that cost me $9.99.
