I recently recorded a pretty long TS file (football game). The audio in the TS file itself is out of sync with the video. I can't swear that it was in sync in the broadcast as I didn't watch it while recording. This is NPVR 4.2.4 on Windows 10 1903. My understanding is that the encoding is done by my Colossus 2. The Colossus 2 is connected via HDMI for both video and audio. I've checked the TS file with VLC and with NPVR itself and see the same sync issues. The audio is AAC LC. Is there any way that NPVR could cause this, or is my Colossus 2 the culprit?

The encoding and muxing is done by the device. NextPVR just writes to disk the data coming from the device. ie, no scope for NextPVR to be causing sync issues.

Thanks Sub, I thought that was the case. Will keep looking. HDMI is going through a splitter. I have not seen anything watching a TV (same splitter). Is there any reasonable chance a splitter could cause this?

I wouldn't think so, but maybe.
