Hi Malte,
As we are also working at this video integration (as you can see in Alessandro Landim's post up in this thread) maybe we can share some efforts to help you on that.
I agree with you that we can't ignore the Ipod format, but in our video approach all you have to do is the ffmpeg output for the video. Maybe we can use both formats: the MP4 for podcasts and FLV for browsers.
However, there are somethings we have to think: I don't know how is the Internet environment where you work, but here in Brasil bandwith is a major problem. If I have an MP4 file, most people just can't download it. The FLV has three advantages:
1 - It's compatible with all browsers
2 - The bandwith use is really lower
3 - Adobe is going to open the Flash format
And there's also another thing to think: today, most people use the Ipods for podcasts in a WiFi environment. Soon, they will be using their phone's browsers, and these browsers will have flash support too. So, I still think FLV is a better approach.
