By Seiyuu shows I mean things like Hanazawa Kana's Hanazawa Kana Hitori de Dekiru kana, Matsuoka Yoshitsugu's Matsuoka Restaurant.
Is there anywhere where one can watch them completely with consistent quality? I can find them in YouTube but it was the one uploaded by some random guy on the internet. The quality also varies greatly, like some only have voice, some with only low res video, and it also miss some chapters (i.e incomplete).
Note 1: limit answer to legal sources. Note 2: not limited to the said shows. They are just examples.
