Sounds to me as though the frontend caches the seektable that has been
created by the recording so far when you first start playback and doesn't
update it during the playback. That means you'll never be able to seek
past where it was when you start watching.

Sounds like a reasonable way to go to me - could be that LiveTV is treated
differently so that it keeps the local seektable cache up-to-date
(although I've not looked at the code to check this).
