Well, the difference is that your message goes to stdout while 
vdr-xine's messages go to stderr.

When you run vdr, is there anything that redirects stderr for example to 
/dev/null, e. g. something like the following line?

	vdr ..... 2>/dev/null

Concerning the example mp3's you've sent me: I've renamed them as 
mentioned below in the log messages to match the cover image mpegs 
you've sent me some time ago, which were renamed accordingly yet.

I too get the lost sync message, but the images still appear perfectly. 
Strange is that I don't get this message for any mp3 file from my 
brother's library. I know that there are several versions for mp3 tags, 
so either libmad doesn't understand the version your software creates or 
your software simply does it wrong. But I'm no mp3 expert ;-)

I'll now try to reproduce this issue on a different machine. Please stay 
tuned ;-)
