I don't think this is covered anywhere else, but I'm throwing it into this existing thread because it fits the title.
The only download I had prior to purchasing the low impact series was the STS Total Body download. I've had it on my iPhone 3GS since I purchased it, and when I use it I use either my laptop (iTunes) or my phone to watch it.
When I purchased the Low Impact downloads, I decided to dig out my old iPhone 3, which has mostly been sitting in a drawer, and use that to keep near my TV so I can work out with the big screen.
I had no problem copying the low impact series to the iPhone 3, but when I try to download the STS vid, I get the following error:
"STS Total Body" was not copied because the video format is not support by your iPhone
My iTunes and iPhone software is up to date, and I've done all the fun stuff like restarting the phone, iTunes, my computer, etc. I'm halfway decent at this computer thing, but I can't figure out why it work on my 3GS, and not my 3G, especially since the newer series works fine on the older phone.
Soo...help!
