I can get your code running correctly on my system (with some modifications, like xv_port). Anyway, since you mentioned the pink bar in your first post, this reminds me of the pink colorkey color used in the old driver. Maybe you should try the latest CVS code to see if it still has the same problem. You can try XvQueryEncodings function. It returns the encoding structure which usually contains max image size information.
