That is the way with some shows these days On Demand. I think a few USA Network shows follow the same pattern - Psych I know for certain and I may have noticed a few others. I think with Psych they are not only the same amount of commercials, but they might even be the same commercials (at least the national ones).
This why I hope DVD/BR stay around for a long time.
1, I like owning the disc so I can play it anywhere, anytime, any machine without some special setup or tweaking the hardware.
2, I don't want my entire Movie/TV collection sitting on my hard drive, regardless of backup strategies, I want a physical disc I own.
3, So far, other than a few companies with obnoxious previews you can't forward through, DVD/BR is a clean, uncut, no-logo, no commercial format in OAR.
If they start cramming the advertising, logo, edited versions down our throats, I will sadly, but simply stop buying.
