If you don't experience any problems there's probably little point. I've been using v1.17 since I got the player and never had issues. There have been reported problems with v1.25 so I did'nt bother. If it ain't broke, don't fix it.
thats what i think but on the bluray display the audio speed is only 1.70mbps when its suppose to be alot higher on dts hd master. there was a post on here a few days ago who had the same problem and after he updated it, it was alot higher?
