Nice to hear it's working quietly. Did you notice any image quality differences between them?
installed windows 7 last night and after an initial struggle to work out what the hell was going on (having come from XP and never having used Vista) I have started davebryce's guide. I now have working DTS-MA and TrueHD bitstreaming from the 5670 through MPC-HC and ffdshow (both latest builds as of 31/01)...
Good question, on reflection I think not. My VC-1 content works much better but I have changed from the projecthtpc setup (MediaPortal, KMPlayer) to that in Davey's thread so I can't put that change down to hardware alone.
Has anyone tried one of the new budget 5450 based cards yet?
Looking at them as they are sub £50, and sub £40 in a few cases and appear to do all I need to update my HCPC.
Software wise I'm running the MyMovies 3 7MC interface with TMT3 for the playback.
