We got an email earlier today alerting us to the fact that Comcast is apparently only offering it's customers 10 channels of Center Ice, instead of the proper 12-20 channels. Neither Mina or I have Center Ice, so we can't personally confirm the issue, however a google search will reveal problems with Comcast's Center Ice package. They appear to be wide spread and not limited to the Bay Area.
There is a thread about it here.
Some good Youtubage about the issue.
Commenters on Working the Corners blog have stated they've been able to negotiate a partial refund due to the discrepancy between promised channels and actual channels. Check the link and scroll to the comments for more info.
Might I suggest idunno723's best discovery ever? http://atdhe.net/
I did have issues with it for the Stars game, but it worked wonderfully for the Phoenix game. I can't guarantee it will work perfectly for all games, this IS teh interweb afterall, but, it's a free alternative to Center Ice.
If you have more info on the Center Ice issue, let us know. We'd like to keep the info as accurate as possible.
