Re: Getting started with libgpod

Hello,

Thank you very much for pointing this out. As I've stated, my device is an iPhone 3G. I think I'll try the old DBVersion trick and let's see whether it works. AFAIK, the postprocess works fine, at least the logs show that
a) the database is written to, and
b) the checksum is correct, because iPod doesn't delete the entries from the database, just doesn't show them. When I tried to implement SQL insertions by hand (i. e., without the checksum), the app (or MusicLibrary.framework???) removed the tracks.
