Big update on this. It would appear I was WRONG {in the other post} although that is because Apple is extremely poor at documentation. I love most of the Apple products and they seems like a great hardware and software company, but I have long maintained that Apple has got to be the leader in poor/misleading/missing/bad documentation and help files.
This is disappointing and it looks like the old AV cable can only be used with the Classic *in conjunction* with the doc station. See this article...
iPod: TV out support

No longer can you use it straight out of the headphone jack. The Feature Guide lists the old style AV cable but then totally misses including a note about needing the dock for that to work. Which would mislead most reasonable people into assuming the Classic works the same as the 5th Gen with TV Out available on the headphone jack.
On a side note, the Feature guide also states the Classic works with Panther (OS 10.3.9) but I already saw a post by someone who bought one, plugged it into their 10.3.9 Mac and immediately got a pop up stating they needed 10.4 to use that iPod. Again, another serious oversight. See this discussion...
Discussion about Classic NOT working with Panther (10.3.9)

Makes you wonder if the Feature guide was largely written before the Classic was finalized and some specs changes, like the minimum Mac OS required.
It is a shame Apple is so poor with documentation. Sorry that I misled you on this, after being led down that path by Apple.
