Videos of the chinese do exist but the main problem is the language barrier. Youtube isn't popular in China so you aren't going to find footage on english websites. A google-video search of wang junxia in chinese (王军霞) brings up pages upon pages of videos, many with clips of the races, so its obvious that full-race footage is out there somewhere. Unfortunately I don't understand Chinese so I cant search as deep as I'd like to.
Hre are some vids I quickly found:
Qu Yunxia circa-2008. She's now a highschool PE teacher and has settled down with a family (3 parts).

You can see the start line for the 1500 in this vid, looks legit to me - as does the track (whether they were clean or not is another matter).

Highlights of the entire 93 meet.

this seems like a "reunion of ma's army" video. quite long with lots of scattered footage and photos; every member of the 93 squad seems to be there apart from qu yunxia.
