Any sources of early silent kung fu on DVD?

[YoungFeiHung]

I'm interested in early silent kung-fu; especially early Kwan Tak-hing WongFei Hung movies. I've done some poking around the Internet but haven't really turned up anything.

Does anyone know if there are DVDs available and where?

Thanks

I'd like to revise my question: I think I was mistaken about Kwan Tak Hing appearing in silent film, it seems his career is post-war (and thus sound).

I'm hoping to get my hands on Burning of the Red Lotus Monastery or anything silent from Pre-war Shanghai. Does any of this exist on DVD?

I looks like the 1938 Mulan Joins the Army is available on region 6 DVD but I'd prefer the silent 1927 Hua Mulan Joins the Army by Tianyi Film Company if it's out there.
