[linux-dvb] pcHDTV-5500 and FC10 (resend, was too big)

I have been trying to get my PCHD-5500 card to work  with FC10. So far I am
able to get  the analog tuner portion of the card to work but not the
digital. Devinheitmueller was pointing me in the direction to look. I am
getting a crash in one of the modules, which looks like it is coming from
the line:

div = ((frequency + t_params->iffreq) * 62500 + offset + tun->stepsize/2) /

The crash is apparently being cased by a zero stepsize. This crash occured
when I was scanning for channels either from mythtvset or Kaffeine, or a
command line program that came with the card. I also have  Hauppague 250
card in the system which seems to work.

If I select the digital tuner from mythtv the application just hangs and I
get a blank screen.

I tried hacking the tuner-types.mod.c file and adding the following lines to
it that I coppied from one of the other cards (though I suspect these values
are not right for this card)

                .name   = "LG NTSC (TAPE series)",
                .params = tuner_fm1236_mk3_params,
                .count  = ARRAY_SIZE(tuner_fm1236_mk3_params),
                //adding these lines copied from above so that we have
no-zero values
                .min = 16 * 53.00,
                .max = 16 * 803.00,
                .stepsize = 62500,

This at least allowed the applications to do the scan without  a crash, but
the net result was that no channels were returned as valid by the
applications, though it did indicate a lock for some of the channels. I am
guessin other informatino is still missing somewhere. Seems like a driver or
something is not being loaded, or the wrong driver is being loaded. Analog
instead of digital or whatever, I don't know.

Any help resolving this would be appreciated. Here is the output from dmesg.
Search for divide error near the bottom. I added the print to show that the
step size is zero.
