Tvheadend

These are streams from TVHeadend 4.0.7 (running on separate hw). The problems seem to happen only with streams recorded from Finnish TV via DVB-T, Swedish TV over DVB-T is fine as are Swedish channels over DVB-C. It has always been this way AFAIK.

This is what happens:
When you watch, the info on programme length and such are wrong:

1.05 is the total length, but if you look at start/stop times, they are the same, what "18.18.12" is, I do not know.

If you try Fast-Forwarding it will sometimes forward, but when you hit "P" it puts you at the start, same if you try typing in a time or using the arrow keys.

Any ideas?
