Might be able to do it in less steps with xmlstarlet, although whether that would end up being shorter overall I don't know - xmlstarlet syntax confuses the heck out of me.

Prompts for your password, or if you're a bit mental you can add your password into the command itself in the format "-u user:password".

mplayer -vo dummy -ao dummy -identify * 2>&1 | grep ID_LENGTH | sed 's/.*=\([0-9]*\)/\1/' | xargs echo | sed 's/ /+/g' | bc | awk 'S=$1; {printf "%dh:%dm:%ds\n",S/(60*60),S%(60*60)/60,S%60}'

Functions: awk bc echo grep sed xargs

You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds.

Someone better at awk could probably reduce this down a lot.
