Hi I have a problem when watching recorded video,the video starts to play then pauses for a second and then starts again,tried a quick search but couldn't find anything related to this but thought I remembered a similar issue with Sd card compatibility.Tried setting storage to device and this appeared to sort the problem,the card is an Ultima class 10 40 Mbs 64gb which had good ratings on Amazon.So I can carry on using device storage which isn't a big problem and hope this sorts it or I can look at a different Sd card,anyone had similar problems and can recommend a card ,thanks
