[QUOTE="Man Pang, post: 1280825, member: 152649"] Absolutely - the hardware is more than capable since the more power hungry MP1 plays back HEVC content with ease. Not content with this situation, I had a think and eventually resolved the issue. As this may be useful to some and possibly a misunderstanding of the usage of the Home Server on my part or possibly a flaw in the design of the Home Server, I will explain below the resolution. 1. I have an HTPC in the living room running MP2 and it plays HEVC video fine. I will call this HTPC1 2. The HTPC in bedroom (which I will call HTPC2) was configured to use the HTPC1 as the Home Server. My understanding was that HTPC1 would be serving the video stream to HTPC2. 3. I looked at my video sources and saw they were configured as SMB sources (on HTPC1) and my thinking was that the Home Server at HTPC1 could not possibly be serving video streams because the video sources appear as though they are directly played from an SMB location. Consequently, this led to number 4 below. 4. I changed the Home Server of HTPC2 to point to localhost rather than HTPC1 but with the video sources still pointing to the same SMB locations (on HTPC1). 5. Played back an HEVC video which had been problematic and lo and behold, the stutter was no longer present! Well, there was initial stutter for a few frames but once it settled down, playback was fine. So this begs the question, when I was connected to HTPC1 as the Home Server, what in the World was MP2 doing that caused the performance issues? The problem I now have is that I have no TV service on HTPC2. HTPC1 is the machine that has TV tuners connected to it! [/QUOTE]
