Are you sure it's a tuning issue and not a tuner module issue?  (Are you
  
sure you're using the right tuner definition?)

Well, I'm not sure what you mean by definition.  Here's my
modprobe.conf and the corresponding output of lspci.

01:0d.0 Multimedia video controller: Internext Compression Inc iTVC15
MPEG-2 Encoder (rev 01)
        Subsystem: Hauppauge computer works Inc. WinTV PVR-350
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at d0000000 (32-bit, prefetchable) [size=64M]
        Capabilities: [44] Power Management version 2

This is all on Fedora Core 4 with atrpms.  Most channels are pretty
good just as they are, but there are a handful of channels that are
distinctly not correct.  For example, channel 72 is fuzzy/snowy
through the PVR-350 but it's excellent when I hook it up direct to the
TV.

Is there something I've missed in the setup?  Any recommendations are welcome...

Thanks,
I think I'm having similar trouble, but with a much larger block of channels (Time Warner Cable in Minneapolis) and KnoppMyth installation.

A PVR-350 card that can tune in channels 2-13 in fine, 14-20 are snow, 21-36 come in fine, then 37-60 are snow and lastly, 60+ are OK

I've also messed with the fine-tuning on mythweb with no success.  I called my cable company and they said they use the standard frequencies.  I've tried the other 1 or 2 (don't remember now) settings for USA in myth setup with no success either (actually, worse results)
