I noticed on the www.tvshowsondvd.com website that "Riptide" is being released in Canada. I have seen a few other American & Canadian shows released in Canada only. I am just wondering why the studios do this? I know if a Canadian company has the rights they can do what they want. But, I am surprised that the American rights holder/studio would allow one country to release and not the other...especially when they are both R1. Anyone in the US that wants "Riptide" can order it. Thus depriving the American rights holder and even American retailers(or etailers) its sales base. Hopefully, someone can answer this. **This does not apply to tv shows released outside R1.
