Issues with Timeshift

I can pause and rewind/fast forward live TV now with the HDD installed but when I'm playing back in time shift mode the playback freezes every few seconds :bangshead: The only way I can get it back playing again is to fast forward a couple of seconds. It's very annoying. I normally only pause a channel for 10 minutes tops while I make a brew or some food. I can confirm that all channels works flawlessly when viewing "live" TV. Any help with this guys?
Cheers
