720P at 60fps is progressive mode.. AFAIK thats a standard for the HD box and can’t be changed their.. Can I ask why? I have no problems playing 720p 60fps on my Pi3.

As to the Kernel issue, I have no issues with the latest kernel either. My Guess is a faulty Power Supply is causing your recordings to stop. This is a well known issue with the HD-PVR and failing power Supplies.
