If you have a mac, I used UnRarX to open the .rar and convert to .flac. Then I used a free program called Fluke to convert .flac files for itunes. To put them on an ipod, go to itunes preferences, import settings, then apple lossless. It worked for me with the July 19 concert, and it sounds great.Forget crappy Windows Media Player and use WinAmp instead!!
You can convert those files for your personal use with SUPER or XMedia Recode.
The download links I gave you are German sites, but the programs are in English.
If you have any other questions, feel free to ask!
