[NTLUG:Discuss] Some background on tomorrow's meeting, Saturday 10/19

[Stuart A Johnston]

My MythTV setup is similar except that I have a single box for 
frontend+backend. Plus, I'm a bit heavier on the storage: SSD for boot, 
2xSATA (1.5TB + 1TB), 1xUSB (3TB, USB was cheapest per MB at the time).

Of course that is way overkill for typical purposes. You really don't 
need a lot of expensive hardware for this. The key is the VDPAU capable 
NVIDIA card to get the HDTV output without taxing your CPU.

A warning for anyone thinking of or doing ClearQAM from the cable 
company, this is apparently no longer mandated by the FCC.  If your 
broadcast channels are not encrypted yet, they may be soon.  This means 
switching to antenna or getting a CableCard tuner.
