[mythtv-users] Hard Lock

[MythTV-at-C4L]

I'm not sure I agree that Gentoo will really help you with this.  If
it's a kernel/Myth/ivtv issue, merely changing the distribution
shouldn't fix the problem.  Isn't the same kernel no matter who's
distribution you use?

I think the thing to do, is to find the right kernel combination and ID
the holes in ivtv/myth that cause the memory leaks/lockups.
