Your comment about the quality of the audio hit home, but sometimes aren't some TV shows broadcast in other formats than simple stereo?
I have a diagram of my set up on the web, but have to post a few more times before I can post it. Ahhhh...being a newbie..
The DVD recorder only accepts 2-channel stereo audio for recording. Standard analog TV is broadcast also with 2-channel stereo. In both cases, you can have matrixed surround contained within the 2-channel stereo. It can be decoded by a receiver/amplifier that has a Dolby Pro Logic II decoder and provide an added center (front) channel and a rear surround channel (heard through both rear speakers).
Most network and other prime-time TV programs have matrixed surround sound with their 2-channel stereo audio. Your DVD recorder will record that, and the playback of the recording will still have the surround and center channel IF the Dolby decoder is enabled on your A/V receiver/amplifier.
Everything discussed above is accomplished with 2-channel analog audio, i.e., the traditional red and white left and right stereo audio connections with RCA plugs and jacks.
Beyond all of that, a commercially-produced DVD often comes with Dolby Digital 5.1 and sometimes DTS (also a 5.1-channel system). To hear that, you need a digital coax or optical (Toslink) audio connection from the DVD player output to the amplifier input. In my case, I have my DVD 5-disc player set up like this for DD and DTS audio.
The only way to get better than 2-channel (with matrixed surround) stereo audio from broadcast TV (or analog cable) is with a digital TV broadcast and a digital TV tuner. Both HDTV and SDTV, when digital, can offer one of several Dolby-standard audio channel combinations The two most common are DD 2.0, which is identical to analog stereo audio, including matrixed surround when available, and DD 5.1 which is identical to the Dolby Digital audio from a commercial DVD.
Satellite TV and Cable TV set top boxes also provide digital audio outputs, which allow them to pass through DD audio provided on some channels and programs they offer.
Most DVD recorders actually record DD 2.0 audio, with some also offering an option to record using digital PCM stereo audio. Still 2 channels only, with optional matrixed surround when provided by the source.
I hope this explains the somewhat confusing TV audio scenario adequately. The bottom line is your DVD recorder recording function and its live TV reception function are strictly 2-channel stereo audio. The DVD playback function supports DD 5.1 digital audio output (and most likely DTS as well) over coax and/or optical connections to your receiver/amplifier that includes a Dolby Digital (and perhaps a DTS) digital decoder.
Good luck with your audio levels problem. I am interested in hearing the outcome.
