As for "specialty channels", I (personally) think we carry more then enough. I know we recently introduced "Salt & Light" (a religious channel). While it may not appeal to you personally, it was a big deal.
That day we had hundreds of callers requesting to have it added on. Then there's "HiFi", "EQ" & "RAD X" ;not sure what the programs are like on these channels as I haven't bothered to watch them (I stick with my usual stations like Bravo, Retro, AUX, DejaView, and once....TVTropolis [they axed that station; damnit!!!!]). My point being, I just think there's a lot of other stuff to watch. But that's just me (personally). But of course I'm sure some dullard out there will be quick to label me as a shill because I happen to work for Shaw Direct, so me happening to think there is a positive side to ShawDirect must be because I'm an employee. Whatever.
As for there being technical issues that are still prevalent, keep in mind that it's not just the provider who can contribute to this. It can (and many times is) caused by the station themselves. So in other words, there are some channels where even if you switched to Bell or Telus or whomever....that exact same station (on another channel number) would have the same problem(s). Not always the case, but it does happen a lot.
I don't know about you guys, but I've noticed that AUX (it's a music video station) is always pixelated. ALWAYS. Very annoying. I've never escalated this matter because I usually watch it when I come home at the end of my shift and the last thing I'm going to do is call in and talk to a call center. I'll make a note of reporting it today though.
Side note : I'm kinda excited as we just received word that the new HD menus are out in beta testing (for employees only). I've heard they're pretty "slick".
