...Follow Me on Twitter... Why is it after I push 1 for English I still can't understand the person on the other end?...

I'm finding that there are server issues with the Mac WBSP. I initially had video/audio quality issues, but it turned out that this was due to a BW cap in beta firmware I had loaded on my ProHD. After reverting to the released FW on my box, I had some difficulty in getting both Safari and FireFox to load up my stream. Once I got it going, it was perfect !

Unfortunately, I can no longer get the WBSP for Mac to load. It gets to the discovering slingboxes stage and the the browser just quits.

I have been using the beta software for about a week. For me the picture is very good in the standard mode...better than sling 1.08. I am very impressed. Not only is the picture better but it is more consistent unlike 1.08 where the image will vary based on the bandwidth. I have been using the beta sling.com software instead of the sling 1.08 Mac clients. I not had an stability issues. I have been using Firefox 3.x. The sound is a bit off at times but not bad (at times out of synch or choppy). There does seem to be some issues with the Comcast "remote" for my Comcast box. When I try and change channels about 75% of the time pushing the channel up/down button does nothing. I would like to see a resizable window. There only seems to be two sizes...the pretty small standard size and "full screen"...when I go to Full screen the image is a bit blurry because of my large monitor vs the sling resolution. I would like to be able to resize the window to intermediate sizes so I can better match the sling.com output with the window size to maintain top image quality. Otherwise, a good start!
