I am trying to transfer music videos from my PC to my iPad via iTunes. I have video files saved on the PC at 16:9 aspect ratio (have tried 1280x720 and 1024x576) but when I import them to iTunes, the ratio gets changed to 4:3 i.e. 1280x720 ends up as 960x720.

The reason I want to preserve the aspect ratio is to stop the image looking horizontally squashed on the iPad. I have spent hours, actually days, trying to figure it out by googling and then trying this and that but no go.

Have tried all sorts of video converters including Handbrake. This is doing my head in and would welcome any advice, pointers, suggestions. What I really want to know is how to stop iTunes changing the ratio.
