Thankyou NeoFLN, this solves a problem I was having with certain files not playing any sound until I seeked them.
This wasn't too much of a problem (except being a nuisance) until I wrote a plug-in for AudioScrobbler, which implemented their rule that if a song was seeked then it shouldn't be added to the Recent Played Songs list. And I wanted these songs on my list.
I am too curious how you found those seek positions, though?!
Cheers.
