[mythtv-users] Temporal 2x vs Temporal-Spatial 2x

[Govindarajan]

Thanks everyone for all the info. From what I read online and in this
thread it looks like sticking with 200 series is probably better for
now, however, the silent 430 may fit the bill and as an addon it does
HDMI audio pretty well. At present I have a noisy 240 doing a great
job of displaying video but obviously very noisy. I'll wait a little
longer and see if xvba/vaapi on AMD Llano pans out well with
mythtv0.25 and probably do away with the addon card. I have Llano
doing the cpu duty but the gpu on it is disabled.

Cheers,
Govind
