Digtal OTA & Analog Cable in Media Center

I'm using this tuner:

http://us.kworld-global.com/main/prod_in.aspx?mnuid=1306&modid=10&pcid=71&ifid=17&prodid=91

It came with Arcsoft TotalMedia 3 and it allows met to set up digital broadcast and analog cable and switch between the two easily. I'm trying to set up Media Center do do this, but as it is I can only get it configured with OTA. I've tried a couple of suggestions I've found elsewhere, but none seem to work, MC just refuses to see the analog tuner. Can any one shed some light on the situation?

Over the air and cable are both Supported by your Card but You don't 2 Tuners and your Default tuner program is just switching between them both.
This is the reason Media Center wont see them both.
Once MC logs the OTA there is not a tuner left to configure.
I have the ATI HD-650 and its the same way!
I just gave up OTA and only use analog cable .

If you want to do the same as me just rescan and choose the analog this time and not digital and MC will log the cable and nothing else.

There is a RegMod that will allow Media Center to Scan And Log all the channels
but they will be mixed in with cable channels.
Also if there is a Recording conflict it wont be flagged,
And therefor end in an error

I have tried the mod but was not very happy with the outcome.

I don't know of the link to the RegMod right now but if I find it Ill post it.
You can probably Google it a few different ways and find it tho.

Thanks for the reply. I've done some more digging and it would appear that the analog tuner is software encoded, which Media Center apparently doesn't support.
