Upgrade-itus has struct me but I have some unknowns. Should I replace my video processor or take it out of the new setup? I am looking at replacing my screen with a Pioneer KRP-500M monitor, 99% decision made. The main source will be a media PC for watching TV and ripped videos and will have a Blu-ray drive inside. I also have a decent seperate DVD player (Meridian 598DP) with SDI output that I use to gain its sound handling features along with the rest of the sound system. The recent release of Meridians Blu-ray compatible HD621 sound convertor might be a way of releasing more options without loss of quality in any area. The DVDO HD+ has been good for me up to now with its (single) SDI input but I know that it won't do justice to HD originals. Regarding the media PC, when I first bought a load of parts for it I got an output card (Sigma X-card) along with a SDI output connection. Unfortunately this has the opposite polarity to the DVD SDI signal, and the HD+ cannot accept this. Since most of the viewing will be from SD Freeview, would this be a good route for that media? Using the MediaPortal software I can assign different codecs for TV / DVD / BLU-RAY etc. so that HD sources would be output via DVI at 1080P. So do I loose the processor from the system or replace it with something? Both VP50 Pro and C2 have two SD SDI inputs but I don't know if they will handle the polarity issue, Radiance does not have any SDI inputs. Any help / advice would be appreciated. Ian T.
