OK, so I was just about to place my order for PDP-504HDE when browsing through this forum I found a thread saying something like: "there are 100s of reasons not to buy Pio HDE models for an HTPC....unfortunatelly the person didn't bother to actually spell these reasons. I was going to build an HTPC (with a Sat card + Ci slots for Euro1080 and Canal+ and an internet connection to store/play HD movies) and hook up 504HDE to it, but now I put my decision on hold. Can someone help me out with this? Should I drop the idea of HTPC and get a regular setup box and DVD? If I decide to get a 50MX1 will I need an optional video cards or can I use my PC's Radeon 9800 Pro? On the other hand, if I get 504HDE, do I need to use the Media Box or can I bypass it?
