HDTV LN-T3253H Connection to iPod via Composite A/V Cable???

Am having absolutely NO luck connecting to my iPod for audio/video playback via a Best Buy Rocketfish branded Composite AV cable. Have scoured the TV manual, the iPod manual, my Samsung (which is really weak in terms of any type of helpful information), Apple.com and varous forums and am at a loss as to how to make this work! Argh!

Looks like it should be simple. In fact, I tested connecting the iPod to a rather old tube TV that doesn't have a lot of inputs (just used the two audio in connectors on the composite cable). Pushed play on the iPod and... viola... sound. I guess that this proves that there isn't anything wrong with the $ 50 cable.

Tried setting it up... uh, multiple times, as I don't have a lot of AV skills and always doubt myself first... to the HDTV. Followed the exact instructions on page 41 on the iPod Classic user guide. The two audio thingies, red and white, matched to the red and white audio L and R of Component 1 on the back of the TV. The three video in thingies, red,blue and green plugged into their respective colors on Component 1 video in inputs on the back of the TV. The iPod dock connector on the cable was plugged into the docking thingie on the iPod. Turned on the TV. Surfed through sources, which are:

HDMI1: This is connected via HDMI, obviously, to a AT&T Uverse TV STB, never a prob there.

HDMI2: Connected, again HDMI obviously, to a Samsung BD-2550 Blue Ray player that always delivers slamming Blue Ray, DVD, streaming Netflix and Pandora. Again, not a problem with this guy.

Cable 3: Dead, as I no longer have cable.

AV1: Wii, no probs with this connection.

Component 1: Hmmm, since the composite AV cable is plugged into Component 1 inputs then this should be the iPod connector...

Navigated to a playlist on the iPod, pushed play, verified that the thing is running and viola, nada. Tried a video. And, on the iPod, I applied these settings:

TV Signal: NTSC (tried PAL also for the heck of it, but learned that this is not typically a USA setting). At any rate, I tried both, without success.

TV Out: Set to "Yes".

The iPod displays a little TV icon in the upper portion of its screen, when I go to play a video, so it recognizes that it is outputting the video to a TV.

Unfortunately, the TV doesn't seem to recognize this! It helpfully pops up an information screen which displays the message, "not supported mode".

Super bummer. My small, POS, tube TV recognizes a simple cable plug in and the high-tech Samsung HDTV which has a gajillion inputs for all sorts of nice toys doesn't? What's up with that?

Oh, and for the record, since I'm telling all of my business anyway, I can't go through a stereo receiver to get iPod content (and, why would I given the gajillion inputs on the TV itself?) Because I recognize my limitations in connecting all sorts of AV devices (and wanted Bose sound on the low end of a Bose budget), I get audio via a little Bose Cinemate system. No receiver is involved, just the boomy thing (Acoustimass module), two little speakers and a connecty thing to hook everything together and to the TV (via Audio L R inputs on the back of the TV).

So, what I am trying to achieve is being able to listen to my iPod, possibly watch iPod videos on the TV while getting the sound via the Cinemate speakers. Seems like this should be achievable. But, I'm missing something probably very simple.

Sorry to be so long in this explanation, but I wanted to try to provide sufficiently overwhelming details on absolutely everything. I am actually an IT geek in my work life (business system applications) and am often held up by support requests that don't explain the issue. The problem is that the home tech stuff leaves me stupified!

So, Samsung tech guys, tell me what very simple thing I'm missing. I'm ready to be embarrassed!
