So using the composite av cable its easy to play iphone video OUT to a TV, but is it possible to go the other way and record analog video from a VCR IN to an iphone? it should be easy if there is an app that will do the analog-to-digital conversion? alot of low-end video cameras will do this but they're still around $100 (aiptek's A-HD, for example). it should be easy for iphone to do it too i would think. Any help would be appreciated.
