Hi all MDL members, I was finding some video in the Internet and downloaded a file of .tp (Transport Stream) video format. When I opened it, my Windows 7 with SP1 64-bit turned nuts and suddenly went blue screen. I restarted my computer and opened the .tp file again, it had the same result. I opened the file using Media Player Classic with K-Lite Mega Codec Pack installed. Nothing strange happened with the other .tp files. I would believe an executable could cause a blue screen. But it was rather unexpected to have a blue screen when I was opening a video. How come a video could cause blue screen? Any thoughts? Thank you.
