@Big_D -- When I record a show on one PVR, I can't watch it on the other ...
What manufacturer & model-number is each PVR?
The older PVRs recorded only onto the internal disk-drive, and did not have any "sharing" software between 2 PVRs, and did not support recording to Shaw's "cloud-server".
The newer BlueCurve TV players should allow viewing any recording on any player.
