It's an N810 with latest firmware upgrade.

I've transferred some files to view on the tablet though I'm getting file format not supported in Media Player (kmplayer and canola2 won't play it either).

I've tried transcoding a video file using someone's post on how to run the command from another thread, being:
mencoder -o "movie.avi" -idx -cache 1024 -srate 32000 -oac mp3lame -lameopts vbr=3:br=96 -af volnorm -ofps 25 -ovc lavc -vf-add scale=512:304 -vf-add unsharp=c4x4:0.3:l5x5:0.5 -ffourcc FMP4 -force-avi-aspect 1.68 -lavcopts vcodec=mpeg4:vbitrate=600:autoaspect:idct=7:ildct: ilme:trell:cbp:mpeg_quant:vrc_buf_size=800:vrc_max rate=600 mymovie.avi

any ideas whats going on?
are there media codec updates which I need to perform?


thanks.
