I can confirm using Maxis broadband, I can't open the above videos. After the advertisement, youtube just shows "an error has occurred". Not even 1 sec of the video is shown. This is very similar to "HTTP-Video" block we applied on our Fortigate device in our office, but I've tested this without any firewall device. So TM is really applying Deep Packet Inspection to certain youtube videos.
