top boxes. Channel tuning is done with the set-top box, under the control of the
MCE remote receiver with IR blaster. The IR blaster is in turn commanded by the
MCE application itself (for scheduled recording) or the remote control (for live TV).
Consult the rest of this document for additional information for connecting set-top
boxes.
3. How can I take advantage of both tuners on NVIDIA
DualTV when I have a single set-top box?
Answer
When using a single set-top box you can only use the NVIDIA DualTV in single-
tuner mode unless an antenna or cable TV (RF) connection is also used. Note that
when you use a set-top box with MCE, channel tuning is done with the set-top box,
and most set-top box can only tune to one program at a time.
Channel changing on the set-top box is under the control of the MCE remote
receiver with IR blaster. The IR blaster is in turn commanded by the MCE
application itself (for scheduled recording) or the remote control (for live TV).
You may receive premium channels only with a set-top box but not a direct cable
TV (RF) feed.
4. I previously used a different TV Tuner card in this system.
Should I uninstall the drivers for that card?
Answer
Yes, if you used an analog tuner card.
Analog tuner cards often come with WDM capture drivers, and digital TV tuner
cards (for reception of digital broadcast) often come with BDA drivers. NVIDIA
recommends that you uninstall all existing WDM capture drivers to ensure that
there is no compatibility issue. The uninstall procedure should be done before you
physically remove the existing analog tuner card.
5. Are there known compatibility issues with the NVIDIA
DualTV card and any systems or motherboards?
Answer
NVIDIA DualTV has been verified to comply with relevant PC specifications.
However, at the time of printing this document, NVIDIA has found a case where
systems with a certain motherboard cannot boot up when the NVIDIA DualTV
card is plugged into a particular PCI slot. The workaround is simply to reinstall the
NVIDIA DualTV card in the next available PCI slot.
In another case involving some versions of another motherboard, the system may
not perform a POST (Power-on Self Test), which is part of the hardware test and
initialization sequence on boot-up. This error may indicate motherboard or power
supply issues supporting this card. Please consult your PC dealer.
