Best Comcast cable box for SD

12-25-2009, 12:45 PM
I recently bought a LG42PQ30 and ordered comcast Digital starter package, for some time I was able to get channels in clear QAM directly to my TV and was pretty impressed by the quality.
Now most channels in QAM are encrypted so I started getting them via Comcast cable box and the quality is very bad now.
I have Motorola DCT700 cable box and this is in Seattle, WA area.

Could you please let me know if I can get some other box and get better quality in standard definition.

There IS no better SD. SD is SD any way you look at it. GIGO !! NOTHING will make it look any better on an HDTV. NOTHING ! HDTVs are meant to display HD signals, not SD. Unless you subscribe to HD programming, you're going to be looking at crap on your HDTV.

But my TV was showing better picture with SD when tuning directly from QAM tuner.

So I am assuming its comcast's box which is converting/downgrading signal at its outputs.
