Here is the list of my weekly downloads for making the commute more bearable.
Windows Weekly – TWIT
I split the podcasts into 15 min chunks
http://mp3splt.sourceforge.net/mp3splt_page/home.php (Open Source) I use the Mp3splt-gtk v 0.7.1 windows file with no issues. Setup is more challenging then the more commercial products. (but its free!)
