So I have the BP50NB40 SVC:NB52, followed the directions on viewtopic.php?f=16&t=22896 and I seem to get lots of a/v sync issues. Im wondering if I should re-flash, or are this many av sync errors normal? These errors are from the regular blu-ray disc Jurassic Park Dominion, non-uhd version. Even with these issues the movies play fine and seem to be perfectly in-sync. The issue happens on every disc that I rip, but they do complete successfully. Its just the sheer # of them. If I should re-flash, what version should I try? Any thoughts welcome.

I was thinking of re-flashing using the method in this thread; viewtopic.php?f=16&t=19634

Thanks!
The method I used to flash in the 1st url;

For the moment, to flash the BP50NB40 SVC:NB52, using the latest SDFtool Flasher, follw the steps below:

1. Flash the drive to BP50NB40 1.03-MK.
2. Flash the drive again to BP50NB40 1.03-MK, this time checking the "bootloader" box.

Now for the crossflash:

3. Select the RECOVERY option and in the pop up, select the BP50NB40 1.03-MK firmware that you just flashed.
4. Select the BP60NB10 1.00-MK firmware in the normal drop box.
5. Click START

Ok guys, did a little troubleshooting on my own. I first started by switching the twin dongle to different ports, no luck. Uninstalled in device manager and rebooted to let it detect and install again, no luck, still a crap ton of issues. After looking at some other threads, this is what I did to fix it.

Right clicked on makemkv properties and under the compatibility tab, I clicked "run as administrator ". Then I replaced that cheap ass double dongle for a very thick gauge / high quality USB type A to USB micro and plugged it into a into a USB 3.2 gen 1 slot. I only have 4 UHD discs at the moment since I just started doing this, but originally after I flashed I was getting these A/V sync issues on every disc. However, after doing what I described above, all 4 ripped with 0 a/v sync errors! Yay! Just wanted to share this in case anyone ever runs into this problem with this drive.

The double dongle is now in the garbage.
