Yes, here is how that went:
[root at nfs ~]# cat /dev/cxm0 > test.mpg
cat: /dev/cxm0: Device not configured
Apr  3 09:59:20 nfs kernel: cxm0: video decoder isn't locked

I decided to run trace on pvr250-setchannel,

ktrace pvr250-setchannel -g 720x480 -s
kdump -f ktrace.out

I believe this is the relevant part, but what it is saying and how to  
fix is over my head:

83386 pvr250-setchannel CALL  open(0x804915a,O_RDONLY,<unused>0x804914f)
  83386 pvr250-setchannel NAMI  "/dev/cxm0"
  83386 pvr250-setchannel RET   open 3
  83386 pvr250-setchannel CALL  ioctl(0x3,SERIAL_SETINVCLK,0xbfbfe8b4)
  83386 pvr250-setchannel RET   ioctl -1 errno 22 Invalid argument
  83386 pvr250-setchannel CALL  writev(0x2,0xbfbfe84c,0x4)
  83386 pvr250-setchannel GIO   fd 2 wrote 53 bytes
        "ioctl( tfd, METEORSINPUT ) failed.: Invalid argument

I put the whole dump online at: http://www.ircpimps.org/fbsd7-pvr250-
