I got the same error; the problem is that the tuner on your card is 
currently unsupported by the pvr250 driver. I was able to use a 
workaround to get the card to load, but I have not tried switching 
channels with it as I'm using an external tuner (cable box) and s-video 
so I don't know if the workaround will give you full functionality.

Workaround:
1) Edit work/dev/cxm/cxm_eeprom.c. According to ivtv-sources, tuner code 
0x63 is a TUNER_TCL_2002N,     "TCL 2002N 5H". The closest supported 
code is 0x55, so you will need to add the line "case 0x63:" in the 
"switch (tuner_code)" statement before the line "case 0x55:"

2) run "make patch" again. I forgot this step the first time I tried the 
workaround which kept the card from loading.

3) make install

4) kldload cxm_iic and cxm. You should now get:
