    I use Cyberlink PDVD7 as my codec with FFDSHOW RAW VIDEO as a filter to do the following in this order;

    Deinterlacing: Tomsmocomp at 3 search effort (or) 5-tap low pass
    Crop&Zoom: 1 Horizontal Maginifaction
    Resize&Aspect: HxV with no aspect ratio correction

    Despite this, video never looks great and I always see doubled scrolling titles, non-smooth fast moving images, etc. These ARE deinterlacing artifacts, correct? The above setup seems to give me the 'best' result, however it is no way near 'acceptable' to my eyes. I have also verified with graphedit that the above codecs are being used by MP.

    I feel I have tried everything, but there must be something that I'm consistently not doing right as most other people don't seem to have these problems for as long as I have been (...years)...



    Hence, I'm looking for any advice (in this large issue) with what I may not have tried yet and what may be worth my while. Surely deinterlacing on PC's can be as good or very close to the quality output by most £££ commerically available pieces of h/w?

    I have had similiar problems for a long time, but at last I'm satisfied (only watching SD-TV).

    My working setup is now:
    ATI HD2600 Pro (but the X1900 should be OK).
    ATI MPEG Video Decoder (on the download-page go to "Individual driver download packages..." and download "Complete Avivo™ Suite for X1000 series products or higher")
    EVR in stead of VMR (needs .NET Framework 3.0)
    In Configuration, Television, select "Deinterlace mode: None"

    In Catalyst CC I have set "Wait for vertical refresh" to "Allways on" (3D) and "Use automatic deinterlacing" (Avivo™ Video)

    Earlier I used ffdshow for picture-enhancement, but don't feel I need it anymore...

    I'd like to give this a further go, however I get the following problems described in THIS thread which is preventing me from scrapping ffdshow :(...

    Have you had any issues as described in that thread?

    This seems contradictory since "Use automatic deinterlacing" means, that the application decides the deinterlacing method.

    In my case I activated adaptive deinterlacing (with pull down detection) in the driver. It is also crucial to select the right codec for MPEG2 and H.264 decoding... I had problems with SD content at first because I accidentally selected the AVC/H.264 decoder for MPEG2 content too :) (I am using PowerDVD codecs).

    It seems like you have selected aspect ratio "Original" in MP which shows the picture without scaling. You might be aware of this, but try S to switch between AR's. "Normal" is preferred.

    I can confirm that!

    I agree, but (from memory) I have had issues with some "low quality"-channels when selecting a spesific method, and have ended up with "Automatic".

    Unfortunately this is not the problem. Original shows a very small picture whilst Normal enlarges the picture but a large (albeit smaller) border is still visible all around... As I said, this problem only exists with Discovery channels among others...? BBC/Chanel4/ITV/Five/ etc are all fine in Original as well as Normal (i.e. fullscreen is filled).
