iPod Nano 7th generation (w/ lightning connector) - will video work with a treadmill? The treadmills at my gym have 30-pin iPod connectors so you can control it and watch video on the treadmill screen. However, the new iPods don't have the old 30-pin connection, but have the smaller lightning connector.

Converter cables are pretty cheap, but I'm concerned that the video playback won't work through the converted cable. Some googling doesn't see to give a clear answer, and I'm not sure if anybody has actually tried it, but I'd like to clear it up before I order the converter cable and try it myself.

Has anybody connected an iPod Nano to a treadmill and been able to successfully play back video?
I picked up an official Apple Lightning -> 30 pin adapter (that set me back $40), and I couldn't get the treadmill to play video from my iPod Nano. The treadmill recognizes that I've plugged in an iPod, but then when I try to browse, it doesn't show any of the video that's loaded on the device, and I can't play anything on the monitor. I've confirmed with an iPad that the treadmill works and plays video just fine from older devices, but it doesn't work with Lightning and an adapter.
