What exactly are you trying to do? Sorry, but the information is really insufficient. We need way more information. Are you trying to perform a recording from a DV camera or from some analog source? Without more information, I can't really be very specific, but keep the following guidelines in mind (which should also cover some common questions and misunderstandings):
- The DV capture options in the program are exclusively for the recording of tape-based digital cameras (i.e. miniDV and HDV). They're not for other forms of digital cameras (DVD cams, hard drive cams). The latter would have to be file-imported from, given their recording format is supported.
- If you are, in fact, recording from a miniDV or HDV tape, make sure to connect the camera via FireWire. USB is not standardized and not supported in Movie Edit Pro for capturing DV.
- If you want to perform an analog recording, you'd need to have a suitable analog capture/TV tuner card in your system to connect your analog source (e.g. VCR, old camera) to. If the analog recording function still doesn't start up and says it cannot connect, the hardware might not be compatible with Movie Edit Pro. Update the driver for a possible improvement and/or use the software that came with the hardware to capture. Then import the resulting video file into MEP for editing.
Any chance you're operating on Vista? When you engage the screen capturing option, the program will try to connect to your audio driver and pick up the sound for your recording from the stereo mix.
In order to successfully record from the Stereo Mix the Windows/sound card mixer will have to be configured correctly. In Windows Vista, Stereo Mix recording is selected by default if you do not have anything plugged into your sound card (microphone or line in). If this doesn't appear to be the case on your system, in order to adjust the mixer properly, go into your Control Panel and select "Sound". In the "Sound" dialogue, select the "Recording" tab. Right-click into the list of visible icons/recording sources and pick the option to display potentially hidden/disabled sources. Then, the "Stereo Mix" option (depends on what your sound driver calls this option) will appear in the list, but will still be displayed as disabled. Right-click on it and select "Enable". Done.
