Rusty,
I am running another test now, with the following services running
exim4
cups
apache2
openvpnas
cups
ntp
I will keep you posted.

Well, I had to ask J
I’d say its ‘divide and conquer time’ like I suggested earlier – enable half (approx) of the services and run the test. If it passes, turn those off and then turn on the other half, rerun test. If it passes, life gets hard, and I’m going to ignore that possibility for now! Whichever test fails, repeat the above with that reduced set of services.
If both halves pass, then there is some interaction between the services, and it’s not so easy as divide and conquer. (but of course, if a service depends upon another one to be fully functional (apache and mysql are likely examples) then you’ll have to keep those services together till the bitter end (as it were)).
However, there is still hope someone here has another idea…

Rusty,
The test was run from 11 PM to 7 AM, so no one in my house was doing anything but sawing logs, as far as I know. Yes, teenagers tend to stay up late, but I would have heard the tv. I don't think any of the other machines are really doing anything at that time as well.
I don't think anyone is using my wifi....I have a 64 character key for AES and mac address filter for security. Yes, I know one can eaily spoof the mac address thing, but it keeps some out. I also have not seen anything strange in the logs.
Rsync is a good idea, but I agree - fragile, lots to set up, but maybe worth a thought if nfs tends to be the problem. Maybe a script to check if a local folder has changed, and then rsync it........

Well, NFS server is less likely (I think!) to cause momentary freezes than the client, but samba MIGHT be an idea. Hopefully someone else here has more experience with the server side of things, or maybe google would help.
On the upload video thing – if you wanted to go to a lot of work, you could put directories on each computer that periodically get rsync’d (or whatever) to the server, so that the family members only need to copy the movie to the directory on their machine and it will automatically get copied across. But that may be more work and fragility than you want J (and might make you more expendable!). but that could get rid of nfs or samba or any such thing. Probably not worth doing if NFS isn’t’ the issue J, so I’d say turn on half the processes and see what happens, as I mentioned before..
Thinking about the system for a bit – first the schedule of when things freeze. Does it line up with anything being done on the client machines? On the TV? What ‘absolute time’ (wall clock time) were those 38 incidents at? (If clients do something every 30 minutes, and they are out of sync with each other, that might explain the variability of the hiccup timing)
Going a bit further afield: Have you verified that nobody is using your wifi for any nefarious purposes?
Just some random thoughts…

I only installed nfs because I started to use this server as a media server, and I wanted my family to be able to add movies to the movie folder on the server. Mediatomb then scans the folder and makes the movies available on our nifty wifi enabled TV.
Would samba be a better choice? The other computers on the network are mac, windows, ubuntu. However, the windoes user has a low probability of adding any movies by herself....;) (no gender bashing here.....I live with four wonderful women, and one of them is a complete techo-phobe, and she is proud of it.....but that helps keep me around, so all is good with the world).
