[MPlayer-users] Bug with software scaler "natural bicubic spline"?

[Andreas]

I use mencoder with this command line:
mencoder /hyper/media/nuvexport/mythmencoder/2061_20080831200000.mpg -o /dev/null \
-vf scale=640:360,dsize=640/360,harddup -sws 10 -nosound -ovc xvid -xvidencopts bitrate=3600

and it seems to be stuck in a loop.This is the output:

The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
VDecoder init failed :(

Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.

When I run gdb and stop mencoder with CTRL-C, it always shows a line like this:
Program received signal SIGINT, Interrupt.
