Samsung BD-C5300 playback problems

[chip75]

I've had my 5300 about three or four months now and I seem to be having playback issues with it. At first it was mainly DVD's that suffered I've gone through four seasons of Supernatural with it and around season two the sound began to cut in and out whn you'd select an episode instead of when you select play all. Sometimes the menus don't even display at all. If you pushed enter on the remote it was like the menu had changed but the picture on the screen had not. The menu screen sound cuts in and out.

Yesterday I played Robin Hood on BD it was fine for about five minutes then the picture started to jump then the picture froze completely.

The firmware is up to date. I bought the player from HMV as part of a bundle with six films to start my collection off (now it feels like false economy). I've been happy more or less with the player but it's getting on my nerves now. Also when you rewind or fast forward the picture is choppy even at slower speeds with DVD's (I thought it would be smooth) it's worse than my Sony DVD player which is nearly ten years old or my Toshiba DVD player.

Has anyone experienced similar problems? I'm trying to remember where the receipt for the bloody thing is lol. I know it's silly but I'd be gutted about taking it back and loosing the 6 free films even if one of them is Mamma Mia! and another Bruno...
