[sf-lug] Is there a way to...

[Mark K. Zanfardino]

Blake,

Thank you for the observation.  Yes, I did observe some of the same
things.  Having only just moved up here last year from San Diego where I
had Time Warner (I was outside the Cox region) I am familiar with the
similarities in services provided.

I switched largely as a function of cost: I have no need for digital TV
at this time and couldn't bring myself to pay more for less after my
one-year introductory price expired.  Astounds prices are much more
manageable.  That and I have a whole other set of issues with cable
television providers that I don't want to get into here.

By chief interest is to see if I can verify my hypothesis that the ISP
is altering packet priority.  I'm not sure what I'll do about it yet, as
I'm not sure if there is any recourse that I could take, but I'd sure
like to know if it's true.

Cheers!

Although I can't find anything to confirm this after a quick google search. Comcast and Astound are very, very, very, similar. I notice that they offer the same Channel package lineups, they both have the feature called Ondemand, their equipment and menus and guide all look weirdly similar. Looks allot like Cox, and Comcast down in southern California. I have a feeling that these two companies are somehow intertwined, maybe astound has bought a piece of Comcast's infrastructure?  This being said I don't think the switching of the service provider will really change anything unless moving to a AT&T or sonic...etc
