[mythtv-users] FC3 less stable than FC1? Getting Cannot allocate memory error

I installed FC1 last year with few problems.  Now I am
trying to install FC3 and am having only moderate
success.  For example, I am not able to get through
step 10. Install capture drivers.  I did search
through the mail list and have not been able to
resolve my issue with "Cannot allocate memory" errors.
 Seems like everything is set up correctly.  Just
don't know what I am missing.  I pasted my
modprobe.conf file at bottom.

Appreciate any help.

Here are the steps and results I get to/through:
