Thanks for your post and welcome to the forums. It's really great having you on board with us in the Community.
I'm really sorry to hear that you're not having much luck downloading shows to watch on your iPad.
You can find a list of the Availability of streaming & downloading recordings from My Shows by channel under the heading Streaming or downloading recordings.
It won't give you the shows but does give you an idea on what channels are more likely to give the option.
Hope this helps.
If you need further information, come back and let me know.
