    Built a custom PC recently and put my Wintv Go Plus (1033) capture/tuner card
    from my old PC in it.

    Never had dropped frames on the old pc but new one is dropping randomly. Plays back fine for
    several minutes then audio and video jumps forward a sec or two. I have CPU stepping
    turned off during recording so my CPU runs full out at 2814mhz. Can't explain it. Didn't do it with an older slower PC so it shouldn't do it with this new faster PC.

    System stable running prime95 for hours (even with an OC to 3.01ghz). Memory also error free
    with microsoft floppy based memory tester. Extended tests 11 passes over 5+ hrs.

    Only thing I can think of ...is ...since this PCIe video card has 256mb onboard memory and up to 512 sharing system ram via turbo cache.... Is it possible the memory sharing is causing an issue? I'm not sure where to disable sharing but it's probably in the bios. I didnt see an option to set video aperture but I might've missed it. Aside from that (maybe) possibility...I'm out of ideas...

    BTW....for those that don't know this hauppage capture card...its software encoded and I'm recording with mpeg1 using the included hauppage codec.

    All suggestions welcome and appreciated.
    Thanks,
    Dave

    First of all, it's great that you gave us all that info, but you should have included your OS in there. If you're running Vista, maybe it's a Vista problem. Lots of people have serious problems with Vista.

    Secondly, I had no idea that Hauppauge made cards that do software encoding. You spent all that money to build out a new system and you're using Hauppauge's cheapest card in it. The PCI based PVR series generally works very well. The PVR-250 and 350 models just work without problems. The PVR-150 uses a different chipset and some people have no problems, others have nothing but problems. The 1600 is too new and I have never used it. The PVR series uses hardware encoding, so generally speaking they work without problems.

    Usually frame dropping occurs when something is using too much of your CPU and the software encoder can't get as much as it needs. Are you doing anything else on the PC while you record? I would definitely no do ANYTHING on the PC while recording with this card. I doubt that memory sharing is the problem. Usually it's a CPU issue, not memory, when you drop frames. If you had one of the PVR cards I think you'd see this problem go away.

    Thanks for the reply. Actually I did include the OS info. Windows 2000 pro.
    It's just before I list specs for my systems.

    I wasn't building an HTPC here and sorta need to give the wallet a rest after building this system which Is why I re-used my old tv card. I realize software enoding isn't the best way to capture and record streams and that the hardware encoded PVR cards are better.

    My reason for this post however is to try and find out why the tv card worked fine with my old PC....and is dropping frames with this new higher performance system.

    If you (or anyone) has any ideas on that specifically it would be appreciated.

    Hmmmm....150 views so far and only 1 reply. Guess I stumped everyone...

    No matter....Issue is RESOLVED.

    Wasn't any of the usual suspects. It was the fact that I installed an a new version
    of WinTV software OVER the old version. I would normally uninstall an old version any
    time I install new software...but ....the newer Hauppauge drivers and software don't
    include the mpeg1 codec. By installing the old version first then the new one over it...
    the mpeg1 codec (and others) that came with the old version were retained once the
    new version was installed over it. This way I was getting the advantage of the newer
    slightly faster GUI and program features but got to keep all the old codecs.

    UNFORTUNATELY....this dual install was apparently the reason for the frame skipping during capture. Uninstalled everything and re-installed just the old version and it works fine even with CPU stepping set to 1809mhz at idle with No skipped frames.

    The learning process never ends......................

    Hardware encoding is the way to go, with cards like Hauppauge's PVR-250/350, etc. Software encoding is just a losing proposition as your post proves.
