Jokiin-
Wow, thanks for replying over here. I wanted to post in the other thread (actually the only thread where I feel I know some people), but I knew this would be totally off-topic over there!!!
So, I'm not sure how I could have mismatched files....??? I reformatted my Lexar 128 gb sd card per the instructions from Viofo. And then I set-up my A129 carefully, ie, did the pin-reset, default settings, etc... - - I put camera in car about 24 hours ago, and have a lot of parking videos and some driving videos. - - Sometimes when I look at some clips, I can see both and front and rear camera views. But right now, I can only see one view at a time.
I was wondering if I could be missing a setting...??? I have pointed the program to the video folder (E: \SD Card...) Sometimes I select the videos using the "movies icon". Either way, I'm running into problems...
What would you suggest??? - - Thanks again for your reply, and I hope I'm not interrupting your dinner!
edit, ps: While this problem occurs, the icon on the toolbar for selecting "screen view" is grayed-out...only hows #1...
