Comment(by sphery <mtdean at thirdcontact.com>):

 0.20.2 is no longer supported.

 8152 MiB (that's not MB--and definitely not Mb ;) is the standard size of
 DVD+R DL.  http://en.wikipedia.org/wiki/DVD#DVD_capacity

 {{{
 DVD-R SL = 2,298,496sec = 4,707,319,808B = 4489.250MiB = 4.384GiB
 DVD+R SL = 2,295,104sec = 4,700,372,992B = 4482.625MiB = 4.377GiB
 DVD-R DL = 4,171,712sec = 8,543,666,173B = 8147.875MiB = 7.956GiB
 DVD+R DL = 4,173,824sec = 8,547,991,552B = 8152.000MiB = 7.960GiB
 }}}
 (my numbers truncated, the wikipedia numbers rounded).

 In mytharchive/mythburn/scripts/mythburn.py in /both/ 0.21-fixes and
 trunk, we see that MythArchive is currently using 4482MiB for SL discs and
 8106MiB for DL discs (line 96, "dvdrsize=(4482,8106)").  (Sure, the DL
 could be 8147, but may have been lowered due to the slop in requantizing
 or something, IIRC.)

 So, basically, you just need to upgrade to 0.21-fixes or fix your own
 legacy copy.
