I had a 5GB MythTV backend for a number of years, ran fine 6 tuners, 7 disks nearly all HD recordings.

When I upgraded the motherboard I had 8GB, that ran noticeably quicker but with a much faster CPU, an i7, when I use a desktop on the machine for some other tasks it was very responsive and the occasional recording glitches I used to have with the old board went away. 

I stole 4GB from that machine just before Christmas when I replaced a failed frontend PC and it's been a little laggy ever since, I nearly ordered some more memory for it earlier today...

Yes, similar here, except for commflagging, doesn't work too well in the UK and I create ipad compatible 720p versions of shows rather than DVDs but the load is likely similar. 

I haven't seen the exact wedged up scenario you describe but I feel that a busy Mythbackend with lots of tuners needs >4GB, probably 6GB is about right, certainly 8GB never hit swap for me :-)
