Local Record NOT mp4

[user_794754978185390_794754978185390]

I have a RLD-810A. Before I acquired an SD card I was recording to local HDD and ftp server fine. The system was creating the appropriate folders and the individual files were MP4.

I installed a 256GB sd card. This looking OK.

However, not sure if related, recording to local HDD gives files labelled (date ?)_ sdk 100 files, no extension. Not readable and in temp folder, different from dated video folder.

The ftp files are fine, correct folder being created and in mp4 format.

Have looked all over settings but can find nothing related to this.
