Yes. The design of HDTV in the US is to use the same channel
frequency and bandwidth for both analog and digital
signals. The same tuner is use on this card for both analog
and digital TV.

The CX238801 chip has the hardware encoder for both audio
and video. Currently the sound sound encoder support is
under development and you must use a sound card for audio.

No. There is only one tuner on the card. MythTV is not smart
enough to handle this restriction.

The card has a 3 band tuner required to support the TV
channel allocation that evolved over the years in the USA.

There is nothing to support this on the Gold card unless
DViCO has changed the design in the last few weeks.
