Thanks for noticing the errors guys. Been corrected, and a new update is available on the first post.
I changed the download location of xSchedule. I'm hosting it now. To me, it is an excellent plugin that still should be available. I open stated that the plugin is not in development anymore, that the developer does not openly support this plugin (may or may not answer any questions), and that the user will use this plugin on their own accord. If Lasse does not want me to host it, please let me know and I will take down the link and move the plugin to the non working section (that would be too bad in my eyes).
I found that xctpvr is now a plugin for ctpvr to somehow use xlobby. can this be used as a plugin in xlobby as well?
Can't answer you, sorry. I've never used ctpvr, nor any plugin associated with it or embracing it into xlobby. The SageTv stuff, I think is more that both programs are open, and in xlobby you send focus to Sage, then in Sage you tell it to goto sleep and focus goes back to Xlobby. I've played around with something like this with Xlobby/GBPVR as well.
