strange bug: MPC rewind produce black output

[Sirber]

With a MKV (x264, HE-AAC), when MPC arrive at the EOF and rewind to repeat, I get black output. If I start the MKV clean, it works, but not if "rewinded".

:(

does it play black more than a few seconds into the file? or is it only the first few seconds of the file?

20 sec. Then, video start very accelerated to sinc with audio (takes 10 sec). At 29 sec, it's ok.
