rtmpdump -- nice software for ripping Flash content, my installation comes from a nice openSUSE software repository
For legal resp. contractual reasons content publishers usually only may provide their content in a streaming fashion not simply for downloading. DasErste.de has very nice content in its Mediathek. They split the URIs for their streaming content in small pieces which get joint again through Javascript within their web pages, but there are nice descriptions like this one, showing how to get to right URIs from those pieces. I found it by Google-searching for mediaCollection.addMediaStream. The recipe: Find a "mediaCollection.addMediaStream" line in the HTML source, actually the one with the biggest figure as 2nd parameter (highest figure = best quality), copy the substring starting with "mp4:" and ending with ".f4v", and start a command like this:
rtmpdump --host "VOD.DasErste.de" --app "ardfs/" --playpath "mp4:videoportal/mediathek/Polizeiruf+110/c_120000/126955/format130594.f4v" -o "Polizeiruf_110--Aquarius.mp4.flv" curl "rtmp://VOD.DasErste.de app=ardfs/ playpath=mp4:videoportal/mediathek/Polizeiruf+110/c_120000/126955/format130594.f4v" -o "Polizeiruf_110--Aquarius.mp4.flv"
How to download Dittsche from WDR.de? Go to http://www.wdr.de/tv/comedy/sendungen/fernsehen/dittsche/Videoseiten/dittsche_videos.jsp! Then "Weitere Videos"! Your choice then! Retrieve the HTML source! Find the pattern "rtmp://*.mp4"!
rtmpdump --rtmp THE_STRING_MATCHED --flv LOCAL_FILE # name the local file like *.mp4.flv!
flvstreamer -- nice software for ripping Flash content, apparently only available on Ubuntu Linux
MP3Info is a program (that is no longer suppied via SuSE-8.2, presumably because it's last release happened quite a while ago), that allows you list and set and that even interactively MP3 ID3 tags. It does not support ID3 version 2 and upwards tags. But then: who generates version 2 tags?
CD-s with MP3 files for use on my Panasonic CD player have requirements regarding file and directory names that are different to reasonable naming conventions for use on a Window iPod.
MP3 tags and ID3v1 or ID3v2 may in theory (although they shoulnd't!) contain contradictory details.
fixmp3 -- a multi-purpose utility, a perl script (I am not sure it knows about ID3v...);
depends on MP3::Info,
which is nowadays part of http://sf.net/projects/pudge
