hello all,

i'm experiencing rare problems with pix_video object, the captured image is not
so good: there is some dropped frames and sometimes image is cutted in
horizontal lines... i'm not shure but i think that it works with very good
quality in the same computer before some changes with my packages.

any idea?

i'm using GEM+cvs version:
GEM: Graphics Environment for Multimedia
GEM: ver: 0.87+cvs
GEM: compiled: Apr 11 2003

i obtain this error: (VIDIOCSYNC: Invalid argument)

i don't know if it's useful but here is some data about my Xfree configuration:

xfree86 4.2.1-6
NVIDIA driver

and in XF86Config-4 i'm loading this modules:
        Load    "bitmap"
        Load    "dbe"
        Load    "ddc"
        Load    "extmod"
        Load    "freetype"
        Load    "glx"
        Load    "int10"
        Load    "pex5"
        Load    "record"
        Load    "speedo"
