AdobeHDS - converted videos stopping midway

[MartianMambo]

I'm looking to migrate some videos recorded with Wowza to Flash Media Server. The videos were captured with the Wowza DVR application and as a result were split into m4fa/m4fv atoms. I've used KSV's AdobeHDS script to recompose these files into a single FLV. At first when trying to stream these via the Flash Media Server VOD app, there was no reported duration. I checked the FLV metadata and there was no duration tag, so I used yamdi to inject the duration metadata.

Now when streamed via FMS VOD, the videos play as expected with the correct duration shown, and I can seek to any point in the video. However, playback will randomly stop midway through. Any ideas why this is happening or what I might look at?
