First I notice your Showtime East is using DTCP which is DRM. If you look at this channel in the web app for the Prime in the Channel Lineup screen it says DRM to the right correct?
Do you have a sdv tuning adapter in your setup for each prime? This is a device plugged into the USB port on the back of the Prime that would be given to you by your cable company along with the Cable Card.
When you play this channel back (when it's working) and look at the tuner status for that specific tuner does it show:
CCI Protection protected-copyonce
if not what does it show for those 2 lines?
Lastly, if you have VLC. Try this for me. Open a network stream (media menu) and paste in:
Does this play?
Thanks for any of that info you can supply!
