When I try to watch my slingbox over the internet I can't get any channels above 20. The lower channels tune in fine. Things like HBO won't tune in.
Do I need to change a setting or something?
What I understand from your post, is that you're missing channels from the lineup.
In this case, you can check the following links about that issue.
Some of my channels are missing in SlingPlayer. I can view them the regular way on my TV, so what's going on?
Channel lineups or channels missing/unavailable in the SlingPlayer onscreen guide
