[QUOTE="Owlsroost, post: 849541, member: 83973"] Well, I just did some interesting experiments using GraphStudio with TsReader.ax and LAV splitter (with LAV video decoder etc in both cases) playing an H.264 HD TV file. The PC is a quad-core Xeon X3430 (2.4GHz) running Win7 64 bit. With TsReader as the source filter, the CPU usage is heavily concentrated on one core - and it starts dropping frames, stuttering etc after 10 seconds or so..... With LAV splitter as the source filter, the CPU usage is fairly evenly spread across all four cores, and it plays smoothly..... So why is TsReader causing such a big change in how threads are scheduled across the CPU cores :confused: ?? Tony [/QUOTE]
