I have two NOVA-Ts (different chipsets). Individually they both work fine. When I put them both in together, my signal seemed seriously degraded and MythTV seemed to get pretty confused (perhaps because it could not tune the cards) - chaos ensued, myth fell apart, so I took out one of the cards.

How are you feeding the signals into those cards?  Remember if you are
using a passive spitter you are throwing away half the power and
supplying each card with 25% of the power of a direct connection.
The Connexant card has coax in and out sockets, The Phillips only has an in socket so I pass the coax direct from my external aerial into the Connexant card and thence, via a short piece of coax, into the Philips card.

I figured whatever I did, I was in trouble as my signal is not the greatest - but this way I figured that at least the connexant would get 100% of what was going. Unfortunately, the Philips card ended up as card #0 and the Connexant #1 (or is it #1 and #2), So i think Myth was trying the card with the weaker signal first and possibly getting upset when it couldn't get a channel on it.

Thinking back, I'm pretty sure that I retuned both of them from mythtvsetup when I put the second in, without a problem....

Would someone mind outlining the best procedure in terms of getting a good signal to both cards and anything else relevant ....

thanks for your time,


Jules

If you have done something more ad-lib then you could be losing even
more of the signal.
