Could you try opie-vlc_0.5.1_test1_arm.ipk from the iPaq feed? It lists 
this on my iPaq opie:

/mnt/ramfs/var/tmp # opie-vlc -p ffmpeg
VideoLAN Client 0.5.1-test1 Natalya
  ffmpeg
       --ffmpeg-dr, --no-ffmpeg-dr
                                  direct rendering (default disabled)
       --ffmpeg-error-resilience <integer>
                                  error resilience
       --ffmpeg-workaround-bugs <integer>
                                  workaround bugs
       --ffmpeg-hurry-up, --no-ffmpeg-hurry-up
                                  hurry up (default disabled)
  Post processing

(default di)      --ffmpeg-db-yv, --no-ffmpeg-db-yv
                                  force vertical luminance deblocking 
(default d)      --ffmpeg-db-yh, --no-ffmpeg-db-yh
                                  force horizontal luminance deblocking 
(default)      --ffmpeg-db-cv, --no-ffmpeg-db-cv
                                  force vertical chrominance deblocking 
(default)      --ffmpeg-db-ch, --no-ffmpeg-db-ch
                                  force horizontal chrominance

                                  force luminance deringing (default 
disabled)
       --ffmpeg-dr-c, --no-ffmpeg-dr-c

disabled)

160x128 says your output frames height and width, this is important to 
but not the most important thing. Your video could well be 5Mbps or 
8Mbps. Perhaps I have not mentioned this clearly enough or forgot to!, 
but with the bitrate of the video off about 750Kb and 240x192 frame 
output size the video on iPaq with opie-vlc (and gpe-vlc, vlc) is quite 
exceptable. Only scaling the output size down does not lower the bitrate 
;-).
