[QUOTE="wowski, post: 212278, member: 56552"] I have a very similar set upto you (similar Motherboard and processor), also using the ATI9250. I noticed in MP 0.2.3 RC3 is more sluggish than MP 0.2.3 RC2, but don't know why. I have still been able to get full 50fps on live TV by a fair bit of trial and error. Try these to see if it improved the performance any. (1) I use the video codec from PowerDVD. Set this up with the PowerDVD application to use hardware acceleration, and hardware de-interlacing. I still use the mediaportal audio codec, and default directsound audio renderer as there seems to be some confilct on my system using the PowerDVD audio codec which I haven't got to the bottom of. Select no de-interlacing from the Mediaportal setup. (2) Make sure the screen resolution is set to the minimum required, e.g. for my CRT TV the lowest available is 640x480.
