The longest I ever saw was a "Mission Of Burma" release that clocked in
around 84 minutes.

But special 80 minute ones are available.  Haven't tried any yet.

I've never managed over 74:50, and it varies from disc to disc, though w/
any particular brand it tends to be the same.  I click on "write disc", it
goes out and queries the drive, and it either passes or comes back w/ a max
time, which means the max time must be written on the disc, because it
comes bacs within a second or so.
