Just got a set of 6' Rocketfish A/V component out cables and can not get signal out to HD TV. They have no support online and say compatible with 3rd gen nano, classic, & touch but not specific to what gen touch. I have an old 1 G jailbroken on 3.0 FW. Will these work and if so only with videos on Ipod? Any help would be appreciated. I have searched and cannot seem to find a definative answer.
