@csams -- it is my understanding that your current PVRs (Motorola & Gateway) have internal disk-drives, to store the recordings, while all newer hardware (BlueCurve & TV players) does not have internal disk-drives, because all the content is stored to Shaw's "cloud". This allows any recorded program to be viewed on all of your future devices. So, not "separated" in the slightest.
Also, note that any "upgrade" to new hardware will not "migrate" your currently-stored content.
The "first generation" of the Shaw Gateway required a Portal device, while the later generation has an integrated player.
Finally, I do not know if your quota on the Shaw Cloud is 3 times 500 GB, or just 1 times 1000 GB.
