I have tried a few of the World Air Routes videos. They are nowhere near the quality of the ITVV videos. But some are okay. Like you mentioned, many are by non-english speaking airlines. I have the Mexicana 737/727 video, and it really isn't interesting at all.
I do have the United 777, JetMagic ERJs, a Canadian MD-80 out of YYZ to somewhere in Cuba, Styrian CRJ2, and Styrian CRJ7, and all are okay. Like I said, they don't match up to the ITVV quality, but they are interesting.
