WebDAV streaming from Netgear Nighthawk M1 4g router

Hi all,

I have recently bought a Netgear Nighthawk M1 4 router. After installing a micro SD card inside, I have tried to access its content from Infuse via WebDAV protocol. I can successfully reach the content of the micro SD card but for any reason Infuse cannot read some videos. The files are ok because after downloading them on the iPhone or iPad, Infuse can read these files without any problems.

The SD card is formatted in HFS+

Do you think this problem could be linked to the WebDAV protocol?

Thank you.
