My PC is a few years old, and has made countless recordings. In the evening there are about three scheduled recordings on average. And since subscribing to the MPEG4 channel a few months ago during the day there are on average a half dozen recordings on that channel. The interesting thing to note is that there have been exactly zero bad recordings for the shows on the MPEG4 channel, all recorded on Tuner1, and all of the bad recordings happen on other channels after that on Tuner1 (for all the ones I checked, which were many).
I've reset WMC a few times before starting this thread.

Did you mean Task Scheduler? If so, that is how I have it setup now, but the trigger is simply at a daily time. I have some ideas on how to get it to trigger off of MPEG4 recordings, but it gets a little complicated to determine that, as well as if there are any other overlapping recordings before restarting the recording service. I want to first iron out the cause-- on my system at least-- and the minimum steps required for the manual workaround, before digging into sorting it all out programmatically.
On top of that I think there is a logistical hurdle with multiple overlapping recordings: Tuner1 MPEG4 recording from 8pm-9pm; Tuner2 MPEG2 recording from 8:30pm-10:30pm; Tuner1 MPEG2 recording at 9:30pm. I can't think yet how to workaround that type of schedule.
That's why I'm thinking the simplest solution is Paw Paw's suggestion of dedicating a tuner. It has some limitations and setup overhead, but might be the most straight forward. Of course unless we figure out a different root cause, or if my FiOS magically resolves itself.
