 Hi,

 commit fbfcc8f1b71b51ff87f09e269d22328be5594f40 (avi: try to synchronize
 the points in time of the starts of streams after seeking) introduced
 severe audio/video sync issues in certain avi files.

 Reverting that commit locally fixes the issue.

 The problem can be easily reproduced with ffplay by seeking in an affected
 file.

 One affected sample file:
 http://files.1f0.de/samples/bb-sync-issue.avi

 I simply cut the file off to limit its size without remuxing it, which
 does cause the duration to be shown wrong, however any seek will still
 break the sync.
