Regarding the tvheadend builds, should they only be used with the matching OE build, i.e. #1015 with #1015?

They're not matched, as such - you can update the tvheadend addon whenever you want, and use pretty much any version you like. Although unless you've got a specific reason to use an older tvheadend addon, you should just use the latest tvheadend version when updating the addon.

Now that the OpenELEC FTP server shows the date/time for each file it does tend to make the build reference (ie. #1022) that I'm adding to the filename somewhat redundant, as the main reason for adding it was simply to determine which file is most recent (as it wasn't always obvious).
