[mythtv-users] CONFIG_HZ setting in Linux kernel improved video playback for me

OK, I'm having problems with 2.6.20, so now I'm trying again with
Mandriva's 2.6.17-14 multimedia kernel.  If I try to manually change the
CONFIG_HZ value in .config to "300" (as I recall someone telling me I
could do), it always gets changed back to "1000" on compile.

Can this in fact be done, or or are we stuck with the 100, 250 or 1000Hz
choices in the older kernels?

Thanks
Bob
