Tvheadend

Same here. Last week was the "Walking Dead" marathon with several episodes straight. TVHeadend has record the first episode four times but with different descriptions (as they were in record chain). So series recording is totally messed up. TVHeadend is the latest build (3.5.245)

A related case:

Wild China offered on BBC 4 series link, first episode early 20140119. Set to record on series link.
Then noticed Episode 1 is also on 20140118. Set it to record individually at 1900.

At 1900 what happens is that two recordings start. Two files get created, one name containing correct date & time, the other containing the date and time for tomorrow's recording.

U have the same problem with git version (3.9.373~g55c2bbb-dirty). I am not using any external EPG source, only what is automaticly grabbed from DVB-T. Mostly I have 2 recordings of the same program, sometimes 3x. For some of them I can see it multiple times in "Upcomming recordings", but mostly there are only ones. In "Finished Recordings" I see it mostly with the same start time, but sometimes the time difference is 1 or 2 minutes.

One czech user sent me information he found about this problem. Czech Television is dynamically updating EPG data to reflect delayed starts of TV shows. TVHeadend does not handle it correctly and it is the cause of multiple recordings of one tv show. It also answers my problem, that there are 1-2 minutes differences of recording start.

I've got the same problem. It occours when the network is changing/updating the starting time of the program. Please see the attached images.

Today I was able to log the events when creating 6 timers for Big Bang Theory:

After first recording started you see how all timers are updated. Then the first episode is recorded 6 times. For me, a feature like "disable automatic timer update" would be very nice!

If anyone is interested to disable automatic timer update:

Hi! Sadly I am experiencing the same issue using version 4.3-1975~g23754f9a6.
I set up schedules for a number of consecutive episodes and they are all automatically changed to the time of the first schedule like the other comments already mentioned.
It seems to be that the German EPG also causes issues.
