Thanks for the info vzwuser76 and also for taking the time to take the picture for me. On the website Alice gave, it stated that that cable was only for video, and you have to buy a cable below for the audio. Yet if it was RCA, then that means only one of those prongs would have actually worked for the audio?
On your cable for the original droid, that plug into the USB was for audio AND video right? You didn't have to get another cable to plug in to your headphone jack?
You are correct. The one I have for the Inc1 is a modified micro-usb to 3 RCA connectors (left & right audio + video).
I've seen setups like what you are talking about in the past (maybe an ipod) where the connector only outputted video and you had to use a cable with a headphone style connector (3.5mm) to output the audio. The all in ones are much easier to deal with for placement as all connections come from a single point (where with this type of setup you have the video out on the side and the audio coming from the top of the phone).
Plus, since nothing has been mentioned for tv-out on the Inc2 other than DLNA, I'd be a little leary forking over cash without knowing if it works or what it will do to the phone itself.
I remember having a minidisc (yes minidisc) player burn up using a 12 volt RF transmitter. I plugged the 3.5mm cable into the headphone jack, smelled something burning, & watched as the lcd display turned black. Luckily the RF transmitter was recommended to me by the Best Buy guy who sold me the player, so they replaced it without question.
THe problem here is you have no physical store to go into to complain to. That makes it possible that in the event of incompatability or damage, they might do nothing. And I'd bet that HTC/Verizon will say you used an accessory that hasn't been approved for use on the device. To big a risk for me.
