Hmmm... you have a 2GHz machine that runs HD video... and you are not using XvMC. Using ffmpeg you are putting the load on the CPU rather than the VGA card, is that right? If that is the case then that should be fine for my machine that is only running a 64MB nVidia. I have disabled the OSD fade but my problems have been that I get stutter simply when the OSD in on screen. I am interested in your DMA issue. Where would I find out what mine is set to? I shall have to experiment further with ffmpeg I think, I only persevered with XvMC becasue it was the first setting I found that allowed stutter free HDTV.

I would say that with a 3 GHz machine you should get pretty good results - I have 2GHz myself. I'm using fairly simple settings, and I don't use XVMC since I don't like the gray OSD. I have it set to use ffmpeg in all cases for any resolution. I also have only two resolution rules defined, one for everything less than or equal to 1280x720, and one for everything greater or equal to 1920x1080. The second case only adds deinterlacing. Maybe you should try using "one field" deinterlacing, as I think it's supposed to be one of the more easy on the computing power ones. Linear blend is also not too computationally intensive I think. I used to use kernel, but actually like the way linear looks on my display better. You can also try disabling OSD fade, and use the least expensive OSD blender. I use softblend - not sure which is less intensive or if that one is itself. Also, for no apparent reason, I came home one day to find DMA had turned itself off on my drives. I was getting stuttering while watching HD until I found that problem. I still don't know how it happened.
