What they are refering to there is something known as broadcast flags. Broadcast Flags are designed to keep people from skipping comercials. The issue is this: with my Bell PVR, I see
none of the comercial; whereas with the old style VCR I would see a 30 second comercial compressed down to 4 or 5 seconds. That's why it has become an issue now.
As for Shaw,
currently they are not employing broadcast flags, however all of their PVR's have the ability to use them; just waiting for Shaw to turn them on.
As for what Shaw is selling as "Time Shifting" is the definition as I had mentioned before. In the past one of the reasons I went with Satellite was because Shaw offered little or no channels from different time zones. Now that they have some bandwidth to play with they are using it.
Myself, I wouldn't be concerned about the broadcast flags. In fact I am looking at picking up Bell's HD-PVR at ~$600, so obviously I'm not worried.
The one thing I will caution you on; once you get used to using a PVR it's hard to use a regular TV after.
Oh, and no worries about the "apparent raggin' on me." I know that you are just trying to get answers to your questions; and that's what forums are for.
