I'm new at this...How can I transfer Podcasts that I collected into Itunes, to my 700p with Kinoma?

Also, after a major crash while playing a podcast with Kinoma 4.01, it is buggy and I would like to delet it from my 700p and relinstall. Is there anything that I need to be carefull of?

I'm leaving to go out of town next week and don't want to be without it...

Thanks
