Mark Twain (Ken Burns) | R4 |
The R1 release of this disc appears to be on two sides of the same DVD (dual-sided, dual layered or dual-sided, single layered I cannot tell from the information on the Internet). It misses out on the extras present on the R4 release, and is also encoded in NTSC. If you take all those things together, the R4 is the clear winner. |
