To help clarify the version numbers for the last two releases:
0.4.9 is the debug version that is helpful for those who wish to contribute.
0.4.9.1 is the GENERAL USE version that most people will want.
I'm getting very close to releasing version 0.5. I hope to do it sometime this weekend!
I just need to finish the part where it makes a DVD from each 120/240 (depending on whether or not the -d/--dual argument is used) minute directory of downloaded videos.
