Hi all. As the title says this week I've started to have problems with every recording I make to my internal HDD. Every now and then the picture freezes & goes blocky, I lose about 8 - 10 seconds and eventually it restarts. Earlier in the week it was an odd irritating glitch, last night it became unbearable, was impossible to watch what I'd recorded and I had to delete.

The HDD is a 500gb new shop install, not some old 2nd hand stuff I had kicking about, there are no signal problems live tv is fine and it makes no difference if the recordings are made off satellite or terrestrial, they are both equally as bad.

I have rebooted, which made no difference and I'm unsure where to look next or rather which order to proceed first.
If anyone has any helpful suggestions to point me in the right direction it will be very much appreciated, thank you.
