On a Windows 7 64bit, I was not able to capture any DV video from a video camera connected via Firewire IEEE1394. I was
|
|
|
|
|
able to control the camera from the capture program (tried *NeroVision* and *magix Video Deluxe*) but only got a black
|
|
|
|
|
screen and no audio.
|
|
|
|
|
|
|
|
|
|
After a little search, I found [this forum post](http://www.sevenforums.com/music-pictures-video/12371-cant-capture-my-dv-camera.html)
|
|
|
|
|
which suggests to switch the IEEE1394 driver from the automatically detected *Texas Instruments* one to the
|
|
|
|
|
***1394 OHCI Compliant Host Controller (Legacy)*** one. After that change, everything worked as expected. This seems
|
|
|
|
|
to only affect 64bit systems.
|
|
|
|
|
|
|
|
|
|
To switch the driver, do the following:
|
|
|
|
|
|
|
|
|
|
1. press <kbd>Win</kbd>+<kbd>R</kbd> to get to the *Run…* dialog, type `devmgmt.msc`, click **OK**
|
|
|
|
|
1. in the *Device Manager*, find the **IEEE 1394 Bus Host Controllers** group, expand it
|
|
|
|
|
1. right-click the **Texas Instruments…** entry
|
|
|
|
|
1. select **Update driver software…**
|
|
|
|
|
1. click **Browse my computer for driver software**
|
|
|
|
|
1. click **Let me pick from a list of device driver on my computer**
|
|
|
|
|
1. select the **1394 OHCI Compliant Host Controller (Legacy)** (that *(Legacy)* is important!)
|
|
|
|
|
1. click **Next**
