DVR recordings wont stream w/o skipping BUT LiveTV plays flawlessly

My issue:

Using NextPVR on my Win10x64 to stream DVR recordings to my Nexus Player in the bedroom. When I attempt it, the DVR plays for about 5 seconds and then starts freezing, skipping, audio out of sync, etc.

However, if I use the same Nexus Player to watch a “stream” of LiveTV from the HTPC, I suffer none of those issues. I can’t figure this one out. Everything is the same hardware/software wise. The only difference is one is a LiveTV broadcast and the other is a DVR recording.
