Long story short... Finally signed up for SchedulesDirect; when adding support for XMLTV somehow the backend was fatally borked -- looks like it actually got uninstalled?! Anyway, it completely doesn't work. Doesn't even appear in menus any more.
So I decided now is the time to switch to 64-bit hardware & finally run multiple tuner cards (I have three HVR-1600) so I did that and it took a week to get it all running. I now have a machine running the latest (29) backend and frontend, I get the (non-XML
SchedulesDirect guide, and I can record and watch shows. The next step is to get my remote frontends working with the new backend. No surprise, they don't "just work" -- the schema is out of date and the frontends need to also be updated to 29. I ran Update Manager and told it to install all updates, but this doesn't seem to have done the trick.So -- how do I take an existing mythbuntu frontend from 0.25 to 29 without just reformatting and starting over?
