Anything over 4X speed is NOT recommended!!!) by using RCA cables/and or digital lines...You should be able to do the same on a PC, Hook the extrenal output from the DVD into the input of the CD writer...

With this method, and please correct me if I am wrong, all you are doing is copying a downsampled 2 channel analog version of the Dolby Digital 5.1 surround version (your TDK dual dvd burner has L and R analog audio inputs). I've done basically the same copying audio tracks from the Dance DVD using the LPCM (stereo) side of the DVD instead of the Dolby Digital 5.1 surround side. If I remember correctly, DVD players will automatically downsample a Dolby Digital 5.1 signal to 2 channels on their analog outs (L and R).
There are 3 audio types on the Rumours DVD-A disc: (1) Advanced Resolution Surround (a.k.a DVD-Audio, which is not compressed) for which you need a dvd player that can decode DVD-A (6 channels at 96kHz/24bit in this case); (2) Advanced Resolution Stereo (2 channels) at 96kHz/24bit; and (3) Dolby Digital which is the standard audio compression method for DVD-Video and is sampled at 48kHz. There's about a 12:1 savings in bandwith with the compression. Dolby Digital encoded audio is generally 5.1 surround, but is also available in a 2 channel format. On the Rumours DVD, it's 5.1 surround.
Without getting into any detail, it's just not practical (and there may be some DMCA issues) at this point to try and copy DVD-A.
The same can be said for the 96kHz/24 bit stereo (digital) version. There are newer DVD players that can decode 96/24 stereo. However, in order to get it playable on a regular audio cd, it has to be downsampled to 44.1kHz/16bit which is the redbook cd audio spec. This results in a significant loss of audio quality.
With the Dolby Digital tracks, you can use the method Brian mentioned or the method of connecting the L and R analog outs of your dvd player to the L and R analog ins of your pc soundcard. What your getting is a downsampled 2 channel version of the Dolby Digital (5.1 surround) audio tracks which will result in a loss of audio quality but may be fine for your intended use.
Alternatively, you can rip the Dolby Digital files to your hard drive (note that there may be some DMCA issues). They'll show up with the extension of .ac3. This is probably the most common pc only method and there are a host of tutorials on the net for ripping audio (dolby digital, not DVD-Audio/DVD-A) from a dvd. Here again you're going to need to downsample the audio (to the correct frequency and also from 5.1 channels down to 2 channels) which will result in a loss of audio quality, but may be fine for your use.
Personally, I don't see the point of ripping/copying the dolby digital tracks to a regular audio cd unless the mix was somehow "rare". Regular audio cd's don't play in 5.1 channels and all you're doing is reducing the quality of an already compressed format. The remastered Rumours cd is supposed to come out later this year anyway.
