Toshiba BDXK100KC won't play regular DVD's.

Blu-ray disc technology continues to improve and advance, so simply having a Blu-ray player in your computer doesn't guarantee that all discs will play immediately.
The Hewlett Packard DV7 Entertainment Notebook has a Blu-ray player, but as the technology advances you have to keep the software and firmware on the system up-to-date to ensure compatibility.

Reboot your Pavilion notebook.
A minor miscommunication between the disc drive and Windows Vista or 7 may lead to a disc read error.
Rebooting clears your system's memory and forces Windows to reload all of your device drivers, which may resolve a minor kink.
Play your Blu-ray disc to see if the problem is solved.
Open QuickPlay and update it.
Double-click the "Update" button to open "Updates and Enhancements."
Double-click "Get the latest QuickPlay updates."
Select "Download now!" on the next screen and wait while the file downloads and installs.
Close and reopen QuickPlay and insert the Blu-ray disc again.

Update MediaStart regularly.
This program tracks updates for your Blu-ray player's firmware, the software coded onto the device to tell it what kinds of discs it can read.
Open MediaStart and select "Update your MediaStart."
Updates are only listed when available, so if you don't see an update, check back in a few weeks.
Each update for the Blu-ray player enables you to play more recent discs, since some interactive features may not be compatible with older software.
Restart after each update.
Update your software on a disc-by-disc basis.
According to HP, some Blu-ray discs have special content protection and require new codes for you to play the movie.
These codes or disc-specific updates are stored on the disc.
If you are prompted to download a free update after inserting a disc, follow the prompts to do so. The updates will be different for each disc.
Check to make sure your player will play regular content if you continue to have issues with Blu-ray discs. It may be that the error is related to the drive, not the type of media.
Try a CD-ROM or a standard DVD to see if the disc responds.
If not, contact HP for a replacement or for drive-related troubleshooting.

i'm having the same problem with regular dvd's. it'll play blu-rays o problem

If the disc that you bought is a bluray disc it will not play on a standard DVD player. But if you ended up with the regular one it should work unless there is a glitch in the disc, if that is the case return the disc.

either a mechanism problem---disc not turning etc or an electronic issue --someone would have to open the unit and insert a disc to see what is happening----also unlikely but possible the optical pickup that reads the discs is dirty or near failure---this will usually show up first on blu ray before a regular DVD.

There may be a issue with the assembly, blu-ray plays with more precision and speed, for some reason it is not slowing down to play the regular DVD's may be a padder motor problem.

is there a multi region hack for the toshiba bd2000kb blue ray so i can play imported dvds and blue ray.

BD-P1000 Update Solution
The solution that worked for me: I went to www.samsung.com/ca and downloaded the Samsung BD-P1000 player's firmware update to my desktop. When opened, I was directed to"burn" a DVD on my computer. I then inserted the new DVD in my Blu-Ray player. The player automatically checked and confirmed player model number and registration and uploaded information from the DVD and the update was complete. The BD-P1000 then flawlessly played the rented Blu-Ray disc of "The Scorpion King".
Thank You Samsung!

It should recognise the discs. If you just bought it new, it's under warranty. Take it back and exchange it.
