Version 0.8.4: Configuration Windows XP SP3. Video: .rm (RealPlayer)
Video source: http://digicoll.library.wisc.edu/Arts/data/video/MmBib/Suzuki/reference/vn018r.ram (downloaded to the hard disk to save bandwidth).
In version 0.8.0, the above video downloaded to the hard disk is replayed perfectly, both the video and audio synced together.
In version 0.8.4, during the playback, the video and audio starts normally, after a short while the video continues but the sound gets stuck (frozen). Replay continues normally, no crash.
Workaround: I reverted back to version 0.8.0.
