    I've got this PCI-E card for $25 just because it claims to have H.264 hardware decode. It did decode H.264 content, however when I attempted to play full HD videos (1920*1080) at full screen, frame rate drops and video shutters.

    While you may think it might be software decoder issue, nope it's not. CPU usage is below 5% (Intel E2140) and whenever windows size is smaller than 1440*900 or the screen resolution is set below 1440*900, all H.264 videos play smoothly. 720p content is perfect under sized or full screen too.

    Now I am suspecting 9300GS does not have full capability to display 1920*1080. It manages to decode full HD video, but not display... strange huh? I've heard people running OK, but so far I really can't tell the difference between these 9300GS.

    In fact, it seems my 9300GS clock rate is faster than theirs:

    Replying myself: Turned off Vista Aero Glass and it worked normally.

    My friend suggsted that 128MB RAM isn't capable of managing so much stuff.

    Try turning on the Turbo Cache to 512mb~ and then try it with Aero

    hardware decoding is nonexistant unless you're playing an actual blu-ray disk under certain circumstances. please see the link in my sig for my media PC worklog, it has a guide on setting up H264 playback. I've managed smooth playback on systems with 32MB video cards and as low as 1.5GHz single core CPU's - trust me, your system is enough even with a 9300 in software mode.
