Potentially stupid question from a novice

I just hooked up the SA 8300HDC to my new Samsung 3253H (720i). Loving the pictures and the sound quality, despite a few early glitches (a couple of frozen pictures; a couple times when I turn the tv on, it says "weak signal" and I have to turn the cable box on and off for the picture to come on).

Here's my question---I keep reading a lot about "pass through" and having my tv convert the signals. What does this mean, and is this something I need to do? I notice the cable box shows various signals depending on the channels and programming (1080i, 720i, 420i have all come up at various times). I read the sticky on the instructions for SA 5300HDC and I am still confused.

Can someone please explain this in layman's terms? Am I fine as is, or do I need to make any adjustments. Thanks in advance.

Pass through means that what ever resolution the channel is sending - it will pass through the STB unmolested and the display will now deal with the signal. If any scaling is required - the display will do it and not the STB

Is this something I need to do with my setup? Will I see a noticeable difference in picture quality? It seems pretty good right now. And, if so, does the setup work the same way as it does for the 8300 HD?

BTW, I should add that my cable box is connected to the TV via an HDMI cable. Does that have any impact on my setup?

Nope - you could use Component - just as good.

If you have Pass Through you should use it because it will allow 720P to hit your display as 720P. This format is only used by Fox, ABC and ESPN.

It is a question of which device has the better scaler in it - the STB or the Display?

You should experiment and try all the different setting to see with your own eyes which provides the best image.

You also might consider running the HDTV Setup Wizard on your STB. The procedure starts on Page 4 of this manual.

Personally I used the Advanced Setup procedure and configured my SA 8300HD for 1080i, 720p and the two 480p resolutions versus the 480i resolutions. I just think the SD picture looks better when the STB is configured that way, at least to my old eyes. Of course this is also dependent on your provider and the firmware installed on your SA 8300HDC device not to mention what looks best to you...:cool:

FWIW, the first post in this thread has a lot of good information that you might be interested in.
