I have been searching for weeks trying to accomplish this and have come up empty. I know canon specifically released the RC-6 with the T2i. It appears identical to the RC-5. I have tried to the RC-5 and RC-1 and can't get either to remotely start or stop video. They work fine as normal shutter release for stills.
Does anyone know if the RC-6 enables start / stop of video? I am just now starting to see them available.
Does anyone have an alternate solution? I do typically carry a decent netbook (n280 oclocked a bit, 2gb ram upgrade) but would prefer wireless / IR options over wired control due to the specifics of the project in mind.
