I have downloaded multiple podcasts and most of them are tech ones so for those I really only want it to download and keep the most current one (on my ipodtouch).

Problem is I downloaded some others that I want to keep all the podcasts, basically language ones.

For some reason itunes doesn't allow you to do this.

I tried creating a "smart" playlist but this didn't really work. Problem is for these podcast it's a mix of video and audio and while I can add all of them to the playlist only the audio ones are synced. I managed to get the videos on the ipod but it won't play the video (only the first frame).
