Hi. I'm new here to this forum; although, I'm familiar with other forum(s) that I've used on various websites before. Anyway, question here: my Apple iPad (64-GB wifi+3G) works great.. however, there's a problem with audio: when I use composite A/V cable (all connected with TV-out on my HDTV), I bought a movie via iTunes last night and I can see the video, but no audio. But.... when I uploaded movies from my Windows 7 computer to my iPad, there IS audio. What gives? I also wished that closed-captioning would work because I'm a hard-of-hearing person. I know it is enabled on the iPad, but... wished I knew why CC won't actually work. :-( Any ideas/suggestions? Thank you very much!
