update from squeeze to wheezy

[lina <lina.lastname@gmail.com>]

Hi,

when I just simply change the

deb http://http.us.debian.org/debian stable main contrib non-free

to

deb http://http.us.debian.org/debian testing main contrib non-free

it popped up something like

gstreamer0.10-ffmpeg depends on libavcodec52 (<< 5:0) or libavcodec-extra-52 (<<
libavcodec-extra-52 does not appear to be available

xserver-xorg-video-nv depends on xorg-video-abi-6.0
xorg-video-abi-6.0 does not appear to be available



Thanks for any advice,
