there are programs that can tell you most info about the disc, such as gspot
that info (bitrate and such) is usually more important then exactly how it was transferred
if you just tell them it was ___ Camcorder > VHS 1 > DVD along with bitrate, frames/sec, audio format you should be ok
there are programs to rip audio too, however lots of dvds use ac3 audio which is compressed already
so unless the audio is pcm you will not have lossless audio
