I got the exact same behavior, with gotham and tvheadend 3.5 beta.
Adam is looking into it, hopefully we'll hear something from him.

I am surprised not too many are complaining about this.

I also have troubles with the timeshift function after resume the paused channel.

TVHeadend is running as a Debian Wheezy VM on an ESXi System and I tried the versions 3.4, 3.4.27, 3.5.231
Tried XBMC on a MacBook and a normal Ubuntu system with the versions 12.2 and 13.0 nightly builds

The TV card is a Digital Device Cine S2 Debian Wheezy system.

A few seconds after I resume the channel I can see stuttering and artifacts. The xvmc.log then shows lots of ffmpeg error messages:

Code:
ERROR: ffmpeg[1924E000]: [h264] mmco: unref short failure

Here the full XBMC Logfile.

I read in the thread that other timshift problems could be solved by checking the unlimited size box. Unfortunately that does not help.
Btw. what is the idea behind the "unlimited size"? Because I can find many files with a size of less than 100MB in the folder. Is it correct? I would expect one big file if the unlimited size is enabled.

Code:
{
        "enabled": 1,
        "ondemand": 0,
        "path": "/mnt/timeshift",
        "unlimited_period": 1,
        "max_period": 3600,
        "unlimited_size": 1,
        "max_size": 2048
}

I used the timeshift folder on a ZFS Raid System, SSD and ramdisk, but also without success.

Any ideas what could cause the issue?

Hello, what is the current status? I'm running stable tvheadend (3.4.27) & XBMC (12.3), can I use timeshift?

Will anything be different with the release of 13.0 which seems to be close?
