Thanks. It just seems odd that I have to plug one HDD into what is essentially another HDD so that the AV can process it.
I was looking at the media players you mentioned, they seem very reasonably priced, but the reviews are pretty mixed.
I only mentioned the WD one, I've had mine for about 18 months and it's been faultless. It doesn't have an HDD though so not sure what you mean there.
