Harddrive-locked Canopus-DV avi files on XP?

    I recently had to salvage a flakey video editing PC that had a Canopus
    DV-Storm capture card and Adobe Premiere 6.5 installed on a Win XP Pro

    Both the motherboard and the hard drives seemed rather intermittant so
    everything was transfered to a new PC (Dell Dimension P4). Not wanting
    to leave important data on any, even remotely, suspect hard drive.

    I could see the Premiere projects on the old drive and view the AVI
    files in Premier and Windows Media Player. However, when I
    disconnected the old drive from the IDE bus leaving only the new drive
    the AVI files copied to the new drive were just a blank window with
    sound. I reconnect the old drive and can see the AVI drives playing
    fine again, but, here's the weird thing, I can also view the AVI files
    on the new drive. I disconnect the old drive and the AVI files on the
    new drive revert to a blank screen again.

    I can't fathom what is going on here but it seems like some DRM scheme
    to lock media files to a hard drive. Can anyone verify these symptoms.
    If it is a DRM scheme of either MS Windows XP or Canopus then this has
    implications for anyone using that platform for video editing. For a
    start, any data backups you make will be no use if your hard drive
    crashes. Also, the MS or Canopus software is acting as if you don't
    own the copyright to your own captured video.

    Currently I am leaving the old drive connected just as a dongle so
    that the copied projects still work.

    I've swapped drives with Canopus files -- in fact drives in a swap bay are a
    regular part of how I work with Canopus files.

    Thoughts: are they Canopus reference files? Canopus does have a legacy
    large file capture system that uses reference files, and moving those is an
    adventure as I understand it. Or is the Canopus codec installed only on the
    old drive? Canopus uses a proprietary codec that avoids an RGB
    decode/encode phase, staying in YUV colour space -- in a Canopus system this
    proprietary DV codec becomes the 'standard' DV codec, though you can still
    use MS-DV files.

    Sounds like a Player problem. Canopus does not lock files. They do have a
    conversion utitlity that is still free, I think. It will convert Canopus
    AVI files to several other flavors.

    Initially I tried the conversion utility to avoid moving the Canopus
    card. This was with a Pinnical card. Same result. Black screen.

    Maybe if this isn't a Canopus thing then it is an XP thing.

    I have installed the latest drivers for the Canopus card. If the
    drivers were missing or misconfigured then I guess I wouldn't be able
    to view the AVI files at all. However, I can view the files on the new
    drive, but only as long as the old drive is also connected.

    Are they by any chance REF AVI's?

    I too have problems with XP. It will not display Canopus files in Media
