For both my 510 and 530 cameras manual recording is not working and never has.  All detection video is flawless and "take photo" works as it should for both.  When pressing manual record button it turns red , counter proceeds and recording notice flashes on screen,. When press to stop it stops and recording saved to memory pops up.  When pressing playback and download then download file is there with proper time displayed but is all grey.  When selecting file it opens, starts playing, time length is correct but screen is then black.

Latest firmware  1.3.3 on both units, both have 225gb sd cards. Purchased and installed the 510w a year ago Nov, the 530ws purchased and installed one month ago.

Any ideas?
