Tuesday before last, I recorded a few trash programs for domestic blis. When watching them, they kept 'jumping', with split second audio drop outs - mainly audio, but some video also. Both C4 programs. I thought my HDD was goosed, but other programs recorded since are ok. I can't recall if other programs were simultaneously recorded, if they were they were watched & fine. I'm ashamed to admit they were Brat Camp & Selling houses. Anyone any thoughts?
