New to digitizing video, having capture problems.

    Hello,

    I'm trying to convert some VHS tapes to a digital format (avi? vcd?) and I
    seem not to be getting it. I have a Buffalo MEG-VC2 board which uses the
    Conexant BT878 chipset. I first tried it on one computer (1.4GHz P4, 384MB
    RAM, XP Home), but I couldn't load the drivers from the VideoXpert CD-ROM
    that came with the board, because they weren't compatible with XP. I then
    dug out of my basement an old P150 with 80MB RAM running Win 98SE. I got
    the card installed and the drivers loaded, but everything hung because the
    old computer doesn't have enough firepower to handle it.

    I then went back to computer #1, did some googling, and downloaded the
    btwdmddrvinstaller5.3.6.1. I ran the install program and set the device
    option to "Generic BT8xx based card without tuner" and installed the
    drivers. In my Device Manager I have:

    **under "Sound, Video, and Game Controllers"**
    Conexant's BtPCI WDM Audio Capture
    Conexant's BtPCI WDM Video Capture
    Multimedia Controller (This entry has a yellow exclamation point on the
    icon)

    I hooked my VCR to the two input ports (audio and video) on the card, and
    opened the Amcap program. In the Amcap status bar, it reads "Conexant's
    BtPCI Capture". When I start the VCR and start capture, nothing happens
    that I can tell. The screen on Amcap is blue, and the status bar says that
    it's capturing (# of frames, time, etc.). However, I get no video, either in
    preview or MPEG2 mode. WMP won't open the AVI file at all.

    My googling for the MEG-VC2 board ended up fruitless since 98% of the sites
    were in Japanese. I've sent an e-mail to Buffalo Technologies for help as
    well. Does anyone here have an idea as to what might be wrong and how I can
    correct it?

    TIA,
    Mike Trozzo

    That yellow exclamation point may be bad. Try uninstalling and
    reinstalling the drivers. However, I also suspect that may be your
    sound card.
    You might have a problem with the audio here, there probably is an
    audio output on the card which you should hook up to your sound card
    input. If not, then you have a card which actually uses the BT878's
    audio ADC and the generic BT878 WDM drives don't support that.
    Not a big deal, but it means you won't be able to capture audio from
    the onboard tuner (if it has one).
    A blue screen is typical when you have the wrong video source selected.
    Select the correct video source. I don't have the AMCap program handy
    but there should be a way to select the video source (composite or
    S-video, whichever appropriate).

    Sam,
    Thanks for responding...replies embedded:

    Those weren't the only listings...Here's the entire list:
    Audio Codecs
    Conexant's BtPCI WDM Audio Capture
    Conexant's BtPCI WDM Video Capture
    Creative SB Live! Value (WDM)
    Creative SB Live! Gameport
    Legacy Audio Drivers
    Legacy Video Capture Devices
    Media Control Devices
    Multimedia Controller <<<<<----- exclamation point here!
    Video Codecs

    There is an output, but there's no tuner on the card.

    There is a selection in the Options > Video Input menu, and it says "Video
    S-video" and under that it says "Video Composite" three times. None of them
    seem to have any effect. Also, under "Devices" there's "Conexant's BtPCI
    Capture" and "SB Live! Wave Device". Both have check marks next to them.
    Also, there's a menu item that says MPEG-2. When I click that, the screen
    turns black instead of blue.

    I would run the BT Wincap installer and select remove drivers. Then
    go into Device Manager and remove the Multimedia Controller and the
    Connexant devices, restart. Then go and install the BT Wincap drivers.
    So this card has?

    S-Video input
    Composite input
    (stereo/mono) Audio input
    (stereo/mono) Audio output

    Ok, where did this AMCap program come from? I don't remember any
    MPEG-2 mode. The AMCap program with which I am sort of familiar
    was a sample program that comes with the DirectX SDK (originally
    part of the ActiveMovie SDK, which went through various permutations
    and repackagings until it became part of the DirectX SDK)

    I will try that today and tell you how things went.

    No...it has:
    S-video input
    S-video output
    (stereo/mono) Audio input
    (stereo/mono) Audio output
    It came from the btwincap site...

    The BT878 has no analog audio or video output capabilities, so
    this board must have quite a bit more than just the BT878. So
    I did a web search and found the product page (its in Japanese
    though, so I can't read it), but there's a very low resolution
    photo of the board and it looks like it has a lot more on it than
    a basic BT878-based card. The BTWinCap drivers might not work
    for you.

    I think you will have to go back to the drivers and software that
    came with the card.
    That's either the basic AMCap program or an extended version of same.

    .....which do not work on XP.

    I believe it's the former.

    I'm going to go back to the 98SE box and try some more things. I got an
    email from Buffalo/Melco, basically saying that I'm SOL trying to get this
    running on XP.

    I think at this rate, I may be better off just going to the store, getting a
    new, up-to-date card, and capture to my heart's content. I've blown 3 days
    trying to get this going. Either that, or learn how to write my own drivers
    :)

    I appreciate the time you've been taking on this...thanks!
