[QUOTE="doveman, post: 672836, member: 67412"] Thanks for offering to look into it. Clearly I don't really know what goes on "under the hood", so I don't appreciate how complicated changing things can be. I'll still offer suggestions though, in case they help you to think of ways around the problems ;) Firstly I would say, put aside linked channels and xmltv for a moment, as a simple user like me who just uses Freeview doesn't use either of them. So if there could be a way to allow the user who uses simple Freeview to designate the tuners so that the mapping can be automated, that would make life easier for them, whilst for more complicated users like yourself you could just not tick that option and carry on using MP as you do now. Obviously the schedules problem will affect even simple Freeview users if channels get a new ID each scan and MP uses the IDs to know which channel it's meant to be recording. Perhaps if the channel name is stored as part of each scheduled recording as well as the ID, after doing a scan MP could try and find that channel name and it's new ID for each scheduled recording. If MP can't find the channel name (because names have been changed), perhaps it could alert the user with a list of scheduled recordings that couldn't be automatically fixed, so that they know to manually reprogram them. Another way to handle when channel names have been changed (like Virgin1 to Channel One), would be to store the channel frequency with the scheduled recording, as often when channel names change they often stay on the same frequency (I think!), and then have MP look for that frequency and it's associated ID after a rescan. This would probably require a lot more work than the other idea though, and as channel names don't change that often it might not be worth the effort, and users will just have to accept that when channel names change, any associated scheduled recordings will have to be reprogrammed manually. Perhaps even the linked channels issue can be automated. If MP stores a list of linked channels and their names, then when rescanning it could delete the links and once it's finished rescanning, find the appropriate channel names and the new IDs and automatically link them back up with the freesat channels. Again this wouldn't work when channel names change, but MP could alert the user with a list of links it couldn't automatically make, so that the user knows to link them manually. Perhaps we could even find or make a list of channel name changes that MP can download, so that it knows which channel names are changing to what and can then automatically link the correct channels up after rescanning (this could be used to deal with the scheduled recordings after channel name change problem as well). Hey, I'm full of ideas this morning. That coffee must gone straight to my brain :D [/QUOTE]
