I found it useful during troubleshooting, but it's not good for real viewing due to pronounced combing (jagged edges) when objects move across the image. Auto allows GPU driver to select method, e.g. on my NVIDIA it is a Linear Blend as I recall.*** In your GPU driver settings beware of Noise Reduction. (In the ATI setup it is called De-noise.) For NVIDIA 9400 enabling this function while simultaneously performing deinterlacing creates excessive load on GPU, as evidenced by extreme stutter/frame drops.The following summary was originally intended for a separate post, but I'll include it here since it relates to above.The NVIDIA GeForce 9400 GPU cannot handle the load of resizing and noise reduction while also performing deinterlacing, and so I've come up with this configuration. It works great on my system since the CPU can easily handle the deinterlacing.Using MediaPoral 1.1 final, SAF v5 100811.1) GPU is set to 70% Noise Reduction. (Other driver settings are default.)This works well even for live TV (either 1080 or 720).2) MediaPortal Config > TV codecs:> MPEG-2 video = MPC - MPEG-2 Video Decoder (Gabest ) . . . . (This performs deinterlacing in the CPU.)> MPEG / AC3 audio = MPC - MPA Decoder Filter3) MediaPortal Config > DVD codecs:> DVD video = ffdshow Video Decoder> DVD audio = ffdshow Audio Decoder4) FFDSHOW Video > my custom DVD preset:> Preset autoload condition: on a DirectShow filter presence = DVD Navigator. . (Any other presets should be configured NOT to load for DVD playback.)> Deinterlacing: ffmpeg . . . . (Any method within FFDSHOW performs deinterlacing in the CPU.)> Resize & aspect: multiply by 2.00; uncheck Process pixel aspect ratio; check No aspect ratio correction. > Settings: Luma = Lanczos, number of taps 3.00; Luma blur = 0.60; Chroma blur = 0.30> Sharpen: unsharp mask = 40> Output: uncheck Set interlace flag; colorspace = YV12Notes on FFDSHOW settings for DVD:These settings are a work in progress, but I'm happy to say it makes a DVD on the hi-def TV look better than the old standalone DVD player feeding component video to the analog TV.I'm using Resize mainly for the Lanczos blur function, which seems superior the other Blur & NR options for cleaning up the DVD picture. When watching a DVD (in MediaPortal) I can choose Zoom = Original, which is now 960 lines (= 480x2), or Zoom = Normal if I want to enlarge it to fill the screen. (In latter case, is this additional resize done in the GPU?)For DVDs with rapidly changing grainy noise (such as Chicago), I have configured a button on my remote to send Ctrl+Alt+B, which engages FFDSHOW > Blur & NR.  There I have enabled Temporal smooth = 2, which helps tremendously.However, be warned that any of the FFDSHOW temporal smoothers will prevent the display of DVD menus that use still frames!!! You have to make sure to toggle it back to OFF at the end of the movie.</blockquote>
