your Ipod touch wont output video unless the cables that are being used are approved by apple.. since they now require a chip to be included with the cables..
On Gen 5 Ipods you could use a standard 3.5mm jack for video but the outputs were diffrent.
Now you have no choice and its only standard def.
Per Steve Jobs, "You want to buy a Apple TV if you want high quality video on your home TV."
I was trying to figure out how to get videos on my ipod touch (1st gen) to play on my tv. I'm wondering if there are cheap / any cables I can get and if they will be AV or better quality. Thanks.
