There is no complete release of MADtv available. This is as close to complete that I have been able to get ahold of.
The following episodes are missing:
S05 E06
S05 E21 - 1st half missing
S07 E24
S08 E23
S09 E08
S11 E22
If you come across the missing episodes, please share them over on /r/DHExchange/ so a V1.1 can be made.
Note: There are two copies of Season 1 & 2. I was unimpressed with the video quality of the DVD rips that were floating around. Someone was kind enough to share the untouched DVDs for season 1 & 2, which I ripped using MakeMKV. They have NOT been re-encoded, since this is for preservation quality. It also made it possible to get almost every special feature (see section below) as well as a better quality copy of S09 E06 - The 200th Episode.
The untouched DVD sources are in the root directory. They are MPEG2 encoded 480i rips with 192kbps AC3 audio in a .mkv container.
---- The Season 1 & Season 2 folder contain the meh quality DVD rips, which are H264 encoded with AAC audio.
