Go to the DVR's set-up screen and see if it has an option for selecting the audio inputs for recording. It may also have separate recording volume level controls whichg are turned down. Just guessing here, but that's the best place to start.
All computers with Windows have a sound recorder on them.
To use a recorder effectively for recording audio, first ensure the recorder is set to the correct input source and recording format. Position the recorder close to the sound source for clear audio. Check the recording levels to avoid distortion. Use headphones to monitor the recording in real-time. After recording, transfer the audio to a computer for editing and storage.
To record your voice on a Toshiba Satellite laptop, you can use the built-in Voice Recorder app or a third-party audio recording software. First, ensure your microphone is properly connected and configured in the sound settings. Open the Voice Recorder app, click the record button, and speak into the microphone. Once you finish, click stop to save your recording.

I find the best way is to set up your stereo next to the computer and have a stereo out from the centre to the microphone in on computer, then configure you sound options to take input from the line in (Start > Accessories > Entertainment > Volume Control, Options, Properties, Recording, Ok select line in) then hit record on your sound recorder as you play the tape... Then after you save the recording burn it to a CD ;) The default sound recorder stops you after 60 seconds of recording and you must hit the record button again... There are ways around this but i recommend using a better program.
i like my sony ericsson satio mobile phone for voice recording.
