HDTV picture quality question...

Here goes...my first post and it's not even audio related...you'll have to excuse me...cause I'm desperate.

I just purchased a Toshiba 34HDX32 and I've got a problem. Watching DVD's are good, I know it'll be better once I get all my cables...I've ordered them and they'll be here in a week. BUT, my main concern is the picture quality of regular TV. I used to have an older ('99) 27" Samsung and when watching TV, it looked not half bad. Now, on the Toshiba, the image is all pixelated, fuzzy, just generally unclear. Anyway, any ideas on how to improve the picture if at all possible?

Here's what I have:
Toshiba 34HDX82
Satellite (Starchoice, I'm here in Canada)
- Yes, it has S-video out but my bettercable Silver Serpent has yet to come...so that'll improve the image...right? In the meantime, I'm using a standard video cable.
- The majority of channels; ALL major stations (ABC, CBS, NBC, local, etc.) have this problem.
- The channels that do look GOOD, and yes, they look real good are the higher channels (Discovery, TLC, the Food network, etc.)
- The satellite receiver itself is hooked up via a standard/generic F-pin/CATV/Coax cable. I'm thinking of replacing this but have no idea what to get...I was looking at MIT but someone out bid me on those. Anyway, ANY help is much appreciated. Thanks for your time!

Er, you also need some means for decoding the HDTV signal. Is your set top box (STB) capable of receiving satellite HDTV channels? (Are there HDTV satellite channels)?

Dunno how it works up north, but in order to get over the air (OTA) HDTV, I needed an HDTV set top box. Although some digital HDTV ready TVs are now being marketed w/HDTV OTA tuners, the large majority of those sold today *do not* have tuners for HDTV built in. In addition, the large majority of the DirecTV STBs are not HDTV compatible--whether satellite or OTA. That being said, I believe that most satellite STBs that provide for HDTV satellite reception also have the capability of doing HDTV OTA. So, you are really looking at shelling out an additional $500 or so to get HDTV reception OTA.

Another thing you may want to try that worked for me initially on my Mits. Get rid of the S-Video connector from the STB to the TV and use a good quality RCA cable. This is assuming you don't have componant out's on your STB. By using the RCA cable you force your TV to use it's internal line doubler. If you use the S-Video you are using the line doubler in the STB which is normally inferior to what is in your TV. This came straight from the Mits rep when I was back at my dealer complaining about the same thing. I took his advice and the improvement was very noticable. It was NOT a slight imporvement, but a large one. Of course, a few months later I upgraded to the HD STB and this was no longer an issue for me.
Also, if your TV has a built in HD decoder do yourself a favor and get the antenna. You'll be amazed and there is quite a bit of over-the-air programming out there in HD. Assuming your local stations are broadcasting it.

Good luck.

Well, I JUST got my bettercables Silver Serpent S-video and replaced that generic RCA video cable I was using. I had a look at some of the problem channels and though there was improvement (thankfully) it's still not perfect. But the channels that I didn't have a problem with before are even sharper...maybe even too sharp. I'll have to do some tweaking when I get home again. :) I've been poking around in avsforum.com (thanks Edesilva) and it's pretty much common knowledge there that picture quality takes a HUGE hit when you have DBS on a large screen or HDTV. Such is life I suppose.

Yeah- you are seeing the limitations of the input software on a highly resolving display device. Conventional broadcast channels are highly compressed and will look pretty poor off of cable or DBS with a high end DTV/HDTV/large screen. I found out the hard way, too. I guess that's why they always use a DVD at the store. Not only to show what it can do (awesome DVD), but what it can't do (improve NTSC cable & DBS).
