For what it's worth, I have a machine running the frontend *and* backend
with 256 megabytes of RAM (minus 8 megs for video RAM) and it works
fine. More memory would be desirable because Linux uses any "extra" RAM
as disk cache, though.
The system is a VIA miniITX box, with a 1 GHz Nehemiah CPU. It has a
single tuner with MPEG2 hardware encoding. MPEG2 playback (at 480x480)
used roughly 50% CPU before I enabled the playback acceleration on the
VIA chipset; after enabling that, it's less, more like 30% if I remember
right. Two caveats: This is analog TV, and I'm not doing transcoding.
I'm actually surprised how little CPU it takes to record and watch
standard analog TV, once you have a hardware encoder.
