[nmglug] .avi on DVD play VLC

[a]

Hi

Intermittent problem received Dvd today has been finicky VLC error 
message say check log where is that log be located?

Have played the DVD in part three tries out of perhaps ten tries no go 
at times seem to override error message?

Have been using open disc ,open files and open DVD alternately the later 
where the error message manafests, I then somehow have stumbled upon the 
three file .avi choices. choose one click on to play, Where I found the 
files is a bit hazy?

Any thoughts on an unraveling strategy? Thanks, Anthony
