I’m trying to convert a completed nDVR stream to an MP4 by calling `getDvrStoresAvailable` on `DvrApplicationConverterContext`. I’ve noticed sometimes the DVR store for the stream is available and sometimes it isn’t. I’ve noticed that it usually isn’t available if its called more than once. I don’t understand why this is happening and how can I make sure that the DVRStore is available every single time? ---

In order to understand why this behavior is happening when called more than once, it will require a support ticket. The only way we can debug this is with full access to your configs and logs - so that we may attempt to replicate the issue.
