So I updated to the new firmware and wanted to test the camera with the new bit rate, so I set it to extreme. Here's the weird part. If I view the video clips of the front camera through Windows Media Player, they run just fine. However, when I view the front camera video files through the Blackvue Viewer (this is on a Windows 10 machine), it's like they're running in slo-mo mode or something. The rear camera video (which is supposedly running at the same time) runs at normal speed - in the same viewing window! Cycling the slo-mo button does nothing, so it's not like it's applying the effect inadvertently. It just does not seem to like the new bit-rate on my front camera files. This is with the very latest version of the Blackvue SD Card Viewer. It also behaves this way regardless of whether I feed it the videos direct from the SD Card via USB 3.0 or copy those files directly to the (SSD) hard drive and watch them from there. Older files at the standard bit rate look just fine.
