So I should have added some details. I would remove the HRV-2250 and HDHR Connect (2 tuner) and replace those with 1 HDHR Quatro.  So only 4 tuners total. No more than 4 HD recordings at a time.

I usually use 2 drives at a time.  My current system has one record group with 2 - 500GB drives so the recordings get ping-ponged between drives.

My PC used by mythtv backend is a core i5-3450S 2.8GHz.

I’ve never dropped video while recording 4 programs at once.  But reality says that I rarely record more than 2 or 3 at a time.

At home the only change would be switching to a HDHR Quatro.  

In my RV is where I want to build a small media PC that would be Frontend and backend together.  I’d probable us the HDHR Connect (2 tuners) in that application. I’d rather not have to add a video card.  I find the Intel GFX in the Core 3 gen or above to be pretty good as a front end.
