I don't think I've ever seen this capability mentioned, so I don't know if it's possible or not. A CD holds 650 MB which is about 80 min of 16 bit/44.1 kHz linear PCM. A DVD holds a Gigabit range amount (can't remember the exact number). But I've never seen mentioned that a DVD recorder could record x hrs of linear PCM 44/16 info. Would be a way to record a bunch of CDs onto just 1 DVD. ?? And then, a DVD-A recorder? SACD recorder? Even if not for digital copies of DVD-A / SACD material, but to upsample and record CDs; or lps in the analog domain, etc. And I think included in the definition of DVD-A is still 16/44 LPCM, so there's another route to many hrs of CD sound quality on 1 disc. ?
