KD48A9 recordings have black frames

[GreatBoo]

Recording freeview HD channels to a 1 month old 1TB WD Elements Portable USB drive, on playback there are multiple black frames displayed and occasional audio glitches during playback. This does not happen when watching the same freeview channel live.
The menu tells me the software is up to date.
I assume Sony are going to release a fix for this?
