Multi-record doesn't seem to be working

[HarryH3]

This morning I was watching a show (on channel 730) while another show was recording on a different channel (channel 630). At 7AM I had set NPVR to record another back-to-back episode of the same show that was recording on 630, on the same channel as the previous recording (still channel 630). I had also set NPVR to record Today at 7AM, on a 3rd channel (612). At 6:58 AM, the stream ended on the show I was watching (channel 730) as NPVR decided it needed the tuner to record the next episode on channel 630 and the new recording on channel 612. I thought that NPVR would just keep using the same tuner that was already tuned to channel 630 and just send the stream to both recordings. Shouldn't it have left channel 730 streaming and used multi-rec to record the other shows? I do have the reverse priority for Live TV box checked in settings. Also note that I have BDA Compatibility set to Media Portal, as suggested by Sub for multi-rec in another thread recently. Just in case that is part of the issue.

Logs attached.

One oddity that may affect this: I didn't go through the Live TV screen to select the show to watch. Instead, I selected the show from the TV Guide screen and then clicked Watch from there. I don't know if this would affect the logic somehow.

On a side note, I was also unable to watch the video that recorded for channel 612 in NPVR, but I was able to watch it via Media Player Classic. As soon as I noticed that I couldn't watch the video, I stopped the recording, went back to the TV Guide and selected "Watch" and could view the video just fine in NPVR, so I clicked the Record button on my remote and NPVR picked up recording the show again and I was later able to view that video just fine. I don't know if this was just a side effect of the tuner confusion or not. Alas, I deleted the botched video recording so I can't upload a sample.
