The "Olympics" official youtube channel has uploaded the top 2 performances from ladies, dance and pairs. Hanyu's performance was also uploaded but I can't find Chan's. Plushenko's and Lipnitskaya's free skate performances from the Team Event were also uploaded.
Sounds like Australian commentary to me, with Belinda and Chris (British Eurosport).
Ugh. I'll keep looking and waiting for Caro's FS to pop up somewhere. It's the only one that I want to watch over and over again at the moment.
Ladies Free Skate starting with Asada, ending with the flower ceremony:
The commentary is in Chinese (Mandarin) and kind of annoying tbh (as a Mandarin speaker myself). They don't really say anything substantial...except things like "wow, perfect, amazing." They also have some pronunciation issues that are kinda...funny like "Adelina Stonie Koba" or "Triple Phillip" but if you can get past all that, it's a decent quality video.
