    I need help please in order to get a TM6000 CD-R King hybrid tv tuner stick with an MPEG2 tv tuner to work for Saorview. I will be using both Three Rock and Clermont Carn to watch tv using it from two different locations. I will need help in setting up the command line if one is needed or anything else instructions wise in order to get a freeware HD MPEG4 codec to work for it. I had to solder the loose usb connector on it to get the Saorview radio stations back on it.:)
    It was working with Freeview from Divis earlier, 23 stations tuned in to it and there would have been more only my Dad's aerial is only a group A aerial, although it is eleven feet at least in lenght, it dwarfs my Triax 100 Element Group A which is around 9 and a half feet in lenght.

    What spec and OS of PC?

    Core AVC and nVidia Graphics with "cuda" enabled in CoreAVC is best MPEG4 H.264 other than "Total Media 3.5" or Windows 7 (which has included codecs),

    Minimum is 1.6GHz Atom + nVidia Ion.
    With graphic card not doing HW MPEG4 & Deinterlacing, you need 3GHz + P4 or a Dual core Duo or better at 2GHz. To struggle for HD H.264 AVC.

    The USB tuner is likely not really MPEG2, just DVB-T and all codec and features depend on applications and codecs and OS installed.

    Well the laptop which I used to test it earlier to watch N.I. Freeview stations had a slight delay at times when watching stations. I have a faster more modern laptop, an Acer Aspire 4520G dual core AMD64 with a 2.1 GHz Turion processor which has a startup failure problem at the moment. Sometimes it starts up and other times it doesn't. The laptop which my Fiancee lets me use now is her old Compaq Presario which has only an Intel Pentium M Centrino 1.60Ghz processor and a bus speed I presume of 590MHz so is probably a little slow. Hopefully I will be able to get my own laptop to work again and then I will buy in a few weeks the same twin tuner usb stick which you tested a couple of months or so ago for Saorview. :)
    Window XP Service Pack 2 is the OS in the Compaq, Vista is in my own Acer laptop Watty and it is powered by an nvidia GEForce 8400m G 128 MB graphics card.

    The GeForce 8400 with CoreAVC codec (cuda enabled in codec settings) for MPEG4, or the "Total Media 3.5" (comes included with USB stick) which has its own Codec that uses GPU for HW acceleration may do the HD.

    All the other configurations probably can only manage SD MPEG4. If you can set video to 50Hz (probabaly only on external screen) you get much better results.

    My GeForce 4 440Go graphics and P4M 1G RAM 1.8GHz CPU laptop can't do broadcast MPEG4 H.264 AVC even for SD with most viewing applications, even with CoreAVC. It needs much more processing than DivX / xVid MPEG4. With "Total Media 3.5" app (which has HW support driver for 440 go / internally included MPEG4 Codec) the laptop does SD Saorview fine and a slide show for HD!

    Note that if you have cuda cored nVidia, selecting "microsoft demultiplexer" and "Enhanced Video Renderer" is best. (on AMD Athlon64 3700+ with GT210 gfx/gpu cpu drops from 70% to 9% on HD, if CoreAVC used and CoreAVC setup has "cuda" enabled)

    "Enhanced Video Renderer" is a part of Windows 7 Direct X that's installed in addition on XP when you install ".net 3" runtime.
    VMR7 (XP original) is fastest if no GPU support. But has no Aspect Ratio Control
    VMR9 (DirectX 9 on XP) does Aspect Ratios properly
    "Enhanced Video Renderer" is very slow if there is no suitable GPU support.
    "Video Renderer" or other slower options than VMR7 don't use Graphics card HW overlay and are very slow, but allow screen shots with Alt PrntScrn key press.
