I think I finally have this licked. I think there were multiple factors: XFS clearly made things a lot better. Skip and fast forward now work much better. The upgrade of myth also improved things. But the real kicker appears to be running zoneminder. I'm not sure yet whether it's the SQL logging that takes place on the primary drive, or the capture card. With the capture card drivers loaded, in addition to stuttering the system is VERY unstable. I'm not sure if it's directly a driver problem, or an IRQ conflict or some other issue. but with ZM off and the driver unloaded (rmmod) the system has been stable for a week, and performing wildly better with mvpmc. something in there is just bad; previously once it started stuttering nothing would fix it except a reboot of the system. Once I'm satisfied everything really is stable (a few weeks of stability), I'll go back and try to troubleshoot the issues with ZM. I still occasionally have stuttering on the mvpmc which I attribute to the memory leak(s?). But where previously a reboot of the mvpmc wouldn't resolve stuttering once it started, now it will. Thanks everyone for their assistance.
