I haven't seen that either. A couple of quick reactions:

1. Unless you have your BIAB files on an SSD, try defragging your hard drive.

2. That song file might be corrupt. As was asked above, does this happen on any other songs? All songs?

3. Are you up to date on program patches and RealTrack updates?

4. Did you try Opt., Return to Factory Settings (also suggested above)? There is a BIAB file that can become corrupt and will be fixed by doing this.

5. Have you downloaded and run the free DPC Latency Checker? The fact that it stops at a certain point sounds similar to problems such as a spike from polling a wireless network every 30 seconds, stuff like that. The DPC Latency Checker will show you quickly if you have this kind of problem.

6. Can you post the .SGU or .MGU song file for us to try? Freeze it first.

7. You can always give PG Music Support a call. Good luck.
