I am also having issues getting conversions working on my iPod Touch, some shows work and others do not, most do not. My recordings will play fine on my PC and look great but most will not sync
to my iPod and when I try playing them on my PS3 I get sound and no
audio.
I have found that on the shows that do not work the frame rates show around 60 frames per second (this is the standard frames per second for HDTV), the iPhone supports a maximum frame rate of 30 fps so this appears to be the problem. Shows that are converted with frame rates under 30 will sync correctly.
It seems like the iPhone profile is detecting the HDTV frame rates and using that instead of encoding with a lower frame rate that is required for the iPhone/Touch etc. If there is a way to hard code the frame rate to 29.97 or 23.97 it should work correctly, but I do not know how to do this.
I really need this profile to work so any help or suggestions from others would be great.
