I think I used to have that problem on my 2.4-based Mythbox until I
finally broke down and added some paging space. After running for a
few days, suddenly IVTV would be unable to allocate buffers and I
would have to reboot.

I had been very hesitant to add paging space because the VMM would
tend to favour caching the recording files and push useful things ---
like Myth itself --- out to disk. It really slowed things down. I'm
not sure whether there were changes made in Myth or the kernel, but it
doesn't behave nearly as badly now.
