Reverting to ios 8.4 on iPad mini v3 cures video lag on Standard...we did update to ios 9.0 and we had a severve lag and the picture quality was also worse, after we reverted back to ios 8.4 all was perfect 0"zero" lag plus we had app crashes when using 9.0 which didnt happen at all before... so for now dont upgrade! until they sort the app.
