By changing the card=0 option to card=42 I was able to get the composite working perfectly and the tv tuner to display static.  However, I cannot receiver any channels at all with tvtime or mythtv or mplayer.  I cycled through all the tuner=XX numbers and nothing seemed to make a difference.  I did a tvtime-sanner scan and it picked up a ton of channels, but when I went to view them in tvtime all I got was static.  The dmesg output:

Anyway, the channels are all static, even though the scan program can pick up signals, the tvtime program cannot seem to display any sort of picture.  The composite, on the other hand, works perfectly.  I have tried using mplayer to try different cable frequency plans and there was no difference.  This is really mind boogling to me because it should display SOMETHING, right?  There is a cable line attached to the first card's tuner port, the other card doesn't have anything connected.

cards without eeprom are always difficult to track for changes.

The tda9887 found seems to indicate the default tuner is wrong for you.

You might try "modprobe saa7134 card=42,42 tuner=43,43" if in NTSC M/N
regions or tuner=38,38 for PAL/SECAM.
