You could go to free-codecs.com and download the dvd codec for your media player. that should do the trick.

Download VLC media player. It is a free movie player that doesn't ask for the decoder (or already has it...not sure). I had the same problem and downloaded the program and it worked fine.

DVD decoders are not free, at least not legally. You can find free ones on places like frostwire.com. Be careful, some are spyware or worse. You can also go to NVIDIA's website and use their decoder free for 30 days, but after that you have to pay. Yeah, VLC works, but for some reason it stopped working on my computer after a day.

Well it could be software or hardware! Sounds like it's software for your computer! You need to find the sofware for your DVD player and install it. The player and or decoder was not installed when you replaced you HD.

Go to http://www.freedownloadscenter.com/Search/dvd_decoder.html for free DVD Decoders Or use a dvd playing software like POWER DVD for which you have to pay.

Hate to rain on others' parades, but... There are many "free" DVD decoders on the internet - and they ARE legal. So you can scratch that one off the list from above. Just do a search. There are some crappy ones, and then there are some good ones. I can't remember off-hand, but here's just one example from a quick search: http://www.download.com/MPlayer-CygMP-/3000-2139_4-10518773.html?tag=tab_pub Also, if you have a name-brand PC like Dell or HP, it should be on a Software Recovery CD somewhere. Double-check or call them. I know HP has WinDVD for most of their desktops, which scans the BIOS before fully installing.
