[QUOTE="AlexanderIanHall, post: 874857, member: 111305"] It's been over a year since my post and I thought I'd provide an update that will help others. My system set up has changed quite a bit since February 2011. [U][B]Server[/B][/U] (was Synology DS408) UnRaid 5.0rc1 20TB storage (mix of 5400/7200 2TB drives) Gigabyte GA-880GMA-UD2H ver2.2 (RealtekRTL8111D/E onboard NIC) AMD Athlon II X4 630 4GB Ram [U][B]HTPC[/B][/U] Windows 7 Ultimate 64bit 60GB OCZ Vertex 3 SSD Gigabyte GA-880GMA-UD2H ver2.2 (RealtekRTL8111D/E onboard NIC) AMD Phenom II X4 955 8GB Ram ATI Radeon HD 5570 (1Gb RAM) MediaPortal 1.2.3 Daemon Tools Lite 4.45.4 LAV Filters 0.50.5 (32bit) TMT 5.2.1.120 FFDShow filters 4422 (32bit) however these are not used Realtek 7.58 network driver ATI Catalyst 11.4 display driver Registry tweak mentioned in original post to switch of Network Throttling MediaPortal Plugins: [LIST] [*]Streamed MP [*]Moving Pictures (Streamed MP) [*]WorldWeather (Streamed MP) [*]FanArt Handlet (Streamed MP) [*]MP-TV Series (Streamed MP) [*]InfoService (Streamed MP) [*]Trakt (Streamed MP) [*]IMDB+ [*]Pandora [*]ShowTimes [*]SubCentral [*]WifiRemote [/LIST] note: I will begin using the Netflix plugin (again) when the new version is released [B]Network Switch[/B] D-Link DGS-108 [FONT=Times New Roman][/FONT] ----------------------------------------------------------- The above specs are far more than is needed for both UnRaid and a HTPC however they happen to be some spare parts I had available to use (other than the SSD). With the drop in price of SSDs I recently decided to buy a 60GB SSD and re-install Windows 7 etc. In doing so I once again found the system was stuttering at times after the installation when playing 40GB BluRay ISO images. Most of my video media is either DVD ISOs or BluRay ISOs. For TV Shows I do a 1:1 conversion of the ISO to MKV (i.e. each episode from a BluRay such as Game of Thrones becomes a 10-15GB MKV For DVD ISOs and MKVs I use the built in MediaPortal player with the LAV Video/Audio filters. For BluRay ISOs I use TMT 5.2 MCE Player. I switched from FFDShow (which I still have installed) to LAV Filters as I found they seemed to work better with multiple audio streams in MKV. I switched from Virtual Clone Drive to Daemon Tools Lite as part of trying to find the cause of the stuttering. As far as I can tell there was no difference in using VCD or DTL. Over the last couple of weeks we have now played many BluRay ISOs without any stuttering at all and I'm comfortable enough to post about my success. In investigating the stuttering I came to a number of conclusions. 1. Mounting a 40GB BluRay ISO in Daemon Tools across Gigabit network with Realtek NICs doesn't stress the network. Playing the BluRays was only hitting around 10-15% network usage on the HTPC 2. Playing Blu-Rays in TMT5 (via Demon Tools) was only using around 5-15% of my CPU with hardware acceleration enabled 3. I have fully working DTS HD Mstr being bitstreamed to my Yamaha Receiver 4. I have working subtitles in bluray, dvd and MKVs 5. If you are outputting audio via a dedicated graphics card and HDMI then disable any onboard graphics card in the motherboard BIOS and don't install any audio drivers other than the ATI HDMI driver (if using an AMD/ATI card) 6. The driver versions and codecs cause the biggest issues with stuttering, and are usually the root cause of the problem. 7.
