Hello,

I have verifed the followin bug for the free nv driver and 
the binary only nvidia driver.

It may be possible that other drivers are affected too.
I'm using mandrake 8.1 with Xfree 4.1.

Here is the bug:

When I create an XV shared memory image of a special size,
for example 800x615 Xlib terminates in the XVShmPut call:

>X Error of failed request:  BadAccess (attempt to access private resource denied)
>  Major opcode of failed request:  142 (XVideo)
>  Minor opcode of failed request:  19 ()
>  Serial number of failed request:  54
>  Current serial number in output stream:  55

which looks like an access out of bound out of the shared memory
segment.
When not using shm and using normal XVPutImage it works.
It even works if I use 800x650 for example.
My experiments showed that the "ratio" w/h is important
to trigger the bug. It looks that if the ratio is 1.23 the
bug always occurs.

regards,

Martin
