What is wrong with  my laptop's SD Card reader?

My laptop cannot read it, and it says it is write protected when in fact it is not. My laptop has no problem reading the same card before.  My camera where this card is used most of the time also has no problem reading the card.

I tried to access the contents of the card by connecting my camera to the laptop, and it worked, but this is a long process and not handy for me. I am more comfortable by  just inserting  the card to the reader slot. Do you have solutions to this glitch? Thank you for your replies.

New Folder

I am using a HDMI connected to my TV, everything seems to work perfectly except intermittently a problem would occur, during playing of videos the signal will randomly disappear for a few seconds an error message "no signal on TV" and after that the signal comes back.

Probably you too encountered problems playing certain copies of DVD. Many times there are DVDs that I cannot play with my desktop’s DVD player. I know nothing is physically wrong with the  hardware because it can perfectly play other DVDs. During attempts with these problematic DVDs I would receive a message telling me about copy protection security issues? What does this exactly mean? Is there a way to overcome this problem? Please help. Thank you.

Windows Media Player

Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card.
