Chroma info??? Well, try some pushy color correction or chroma key on dv and you'll know how chroma info sucks...
Generation dubs are ok, provided they're done in native dv (firewire) or SDI.[/quote]
Again, not trying to be a snob, but you are confusing the technical specs of the format and NLE. Have you ever tried doing keying with Avid AVR 77, BetaSP and its own keyer? About as bad as any DV key. Using a DV deck with SDI, you can go to Symphony and color correct and key in uncompressed 4:2:2 till your heart's content.

Second, DV is 4:1:1 but it does not mean you have to stay in that color space during post.
Third, BetaSP's chroma bandwidth is actually smaller to DV, thus less color info.
If generation dubs is OK in DV, then it must be plain horrible for Beta, since in DV it a exact duplicate.
