[pxc] Problems with pxc 0.81, pxc_xgrab, pxc_grab

[Irem Stratmann]

Hi,

I have some problems running pxc_xgrab and pxc_grab. 
I have installed the 0.81 Version, pxc_load and pxc_live etc. run well.
But I can't grab any image. 
Actually I want to grab sequences of low-resolution sequences. Pxc_grab
returns the system message
'pxc_grab: /dev/pxc0pgm: getsequence: device is busy '

What should i do to get it running? I know that the same card (PXC200)
was running under pxc0.28 under Kernel 2.2.18 but now I changed to 2.4.0
so I need help!
 (the installation and memory allocation for DMA were completed
successfully)


Thanks,

Irem
