Video ts won't open

Mad dog 8X dvd writer
Won’t play new sony movies. Video ts folder says no files found ?
Windows media does not play new bought movies like Casino Royal, Blood Diamond,and a good year. I have updated firmware but it made no difference.
Do I need to buy a new dvd writer? Everything but Sony plays OK. Can anyone help?

Nope, clean the drive and install an actual dvd player like VLC tool.
