I have the Samsung LN52B750 using the Samsung PC Share software 2.0. I have no trouble sharing folders pictures, music, and video. The issue is losing medis file recognition after it plays for variuos periods of time. I have not been able to watch a full movie without this happening. I will un share, re-boot, and share the specified folder again and it will play for a while and it will lose file recognition again. I am running an external hard drive through the computer to a router. LAN cable from router to TV. Running windows XP
