Moreover, for QEMU, it's only interesting if the card exports a RGB visual for you (which is the case of the NVIDIA drivers but not, last time I checked, on some ATI drivers in XFree). If you display the graphic 'as is', I do not see why Xv should be faster than plain XShm. Lionel -- Lionel Ulmer - http://www.bbrox.org/
