This just showed me how much data mplayer already dumped from jazz.net[1] (streaming the videos was not an option - the servers were too slow)
Pipes like this are really useful. My girlfriend uses a similar command for displaying the remaining battery percentage (maybe she should just install python-wmii)
1: mplayer -playlist "http://play.rbn.com/play.asx?url=ibmpdc/pdc/open/wmdemand/may07/jkellerman/17eclipse.wmv" -dumpstream -dumpfile jazz2.wmv and the first video was dumped the same to jazz1.wmv
