poop on a stick...your right!!!
You mean it's not "good enough"? You can see the action and hear the sound correct? Your just being picky!
My stand alone Tivo looks better on my SD 27" Sony compared to my 34' Sony HDTV. It's normal.
What you have experienced is standard. SD on an HDTV (especially LCD's I understand) looks just like poop on a stick. It's called HDTV buyers remorse. It happens when you realise 95% of everything is still SD and you just spent $$$$ and the picture looks worse than a $20 1985 13" Zenith CRT from the flea market.
Don't worry it will only be 5-10 more years (maybe never) till we're swimming in HD content, hopefully your DLP TV still works by then.
The current state of HD anything is sad. My advise its to hook it all up the most conveinent way and try to live with it. After a few years you'll get used to it.
Like I always say:
