Playback problem with NFS sourced videos

[digifuzzy]

Using VLC version 2.5.12 on two Android mobile devices.
Devices: 1) Samsung Galaxy Note3 phone[Android 5]; 2)Samsung Galaxy Pro Tablet[Android 5.1.1]

VLC can play mp3's or music files from an NFS network share without problem.

Problem is playing any video file(avi,mkv,mp4) from NFS share. VLC will, sometimes, give the spinning pylon cone then just revert back to "Local Network" location last opened.
NFS shares are accessible from desktop computers and desktop version of VLC has no problems with these video files.

I am unable to grab a log (as suggested elsewhere from google searching). Logging can be started, but when I attempt to playback, it fails then I go back to the log settings, all controls for logging are disabled - I have to force stop the application.

Suggestions.

In all cases, or just AVI?

All video formats are affected.
I should note, playback had worked previously but stopped recently (last update?).

OK, please share logs.

As stated in OP, I am unable to obtain logs. Logging can be started but controls for logging are greyed out and unavailable once started. A search in the file system did not reveal a log or tempory file.
