Thanks for your help!
Found my problem, I was being a douche bag and not following the instructions. I need to have the files in a folder, not just on the drive.
Thanks Phillips for this upgrade!
I have also been a douche bag myself. I didn't know that I need to put those files in folders. I think I learned something new. Thanks for that. http://imagicon.info/cat/12-19/vbulletin-wink.gif
I updated the firmware of my player BDP3200x/78 with the latest version available. Now he is with version 1.73. However, my player still with the problem of aspect ratio of movies in mkv files as Philips only implemented this fix in the 2:38 version of the System Software. Why this correction was not made in version 1.73?
System software version 2:38
"Fixed the issue MKV aspect ratio - 4:3 / 16:9 would Normally display."
System software version 1.73
