I bought this to view videos from my ipod on the tv but was a bit apprehensive because reviews of similar products suggested that they did not work due to blocks put in place by Apple. However, as it wasn't expensive & I didn't want to throw £30 in Apple's direction I went ahead. Got the cable today and it does what it says on the tin. It works great with my ipod touch and I can now watch my itunes videos on the w/s tv. Cool. There is a loss of picture quality with some videos but this is caused by the quality of the source material, ie, don't expect some lifts from YouTube to be of HD quality, but if you sourced your video from itunes store or similar, you should be ok. The quality of the picture, in other words, is not a reflection on the quality of the cable, but rather of the quality of the source file and the size of your tv screen.
