A friend of mine used to own one. He had bad luck with it. Extra features with hddvd would refuse to work. I believe this is a shortcoming with combo players.
He was happy to get rid of the machine. Firmwire was a big mess i was told. Playabck issues.
On the other hand it may have been bad luck. Myself i had bad luck with sony in the past so none of that for me no more
