As you can see from my specs, my hardware isn't very powerful. However, if I download a TV show from the internet, I can usually play it just fine in media portal. But I seem to have a very hard time playing files recorded from the TV Server. For example, a 45 minute tv show I download from the internet is about 350mb and uses about 50% of my CPU to watch. A video file recorded from my Analog Cable TV is much larger, and uses 100% of my CPU to watch after it has been recorded (which basically locks up Media Portal). Is it possible to make the TV server create smaller or different type of file that would take less CPU to play back? Will a different decoder make any difference? Any other ideas?

    I am surprised you even managed to get MP to load, let alone play anything, that by far is the biggest problem you have.

    It's the bitrate the files are recorded at that makes the difference.

    You would be far better off getting a cheap graphics card thats DX9 compatible, preferably with 256mb of ram

    Unfortunately, I only have 1 pci slot and it is being used by by tuner (though I think this card is DirectX9 compatible). I just downloaded the Cyberlink PowerDVD 8 trial, and I can watch a 1GB, 1 hour long recording at about 15% CPU. But from within Media Portal, this mpeg doesn't work at all (with the cyberlink decoder or any other decoder I have installed). Is it possible to change the recording bitrate? Any other ideas to make this work?
