@beastie831 - DroidPlayer or DroidBOX? We seem to have had some confusion between ourselves, DroidPlayer and DroidSticks recently! Whether us or DroidPlayer, knowing which add-on and specific stream will help us/them.
@RTCarr - If you want quicker access to an add-on, search result for a TV series, or a specific episode, then instead of clicking the OK button on something, use the MENU button on your remote (if your remote has a QWERTY keyboard you can also use the C button). A menu will come up, select the option that mentions adding to favourites. Now, when you're next at XBMC's homescreen, click on the little star icon, next to the icon you use to exit XBMC. On the right hand side you'll see a new menu appear. Press the Up arrow a few times on your remote to jump directly to the end of the list. If you click on the new favourite you've just added, you'll be taken back directly to the area/link you've just added.
Re prioritizing certain hosting comany's links to video streams, that is down to the author of the add-on. A few of them have implement this sort of feature. To check, again don't click OK on the add-on you want to look at, press the Menu or C key again, this time select Add-on Settings, and look through the different tabs of options (if there are any). If you have the option to prioritize certain hosting companies, then make a note of which ones you've found to work well for you. I've noticed that since changing internet provider and physical location, different hosting companies are now faster for me. Ah, just re-read my last post, I'm repeating myself, sorry. Some add-on's authors have a forum thread (google the name of the add-on and XBMC to check for forum threads on the internet), where they might be happy to be informed of dead links that need pruning.
