My sony blue ray wont play hd movies. - Sony BDP-S300 Blu-Ray Disc Player

SOURCE: blue ray player wont play blue ray ''Kung Fu Panda'' disc.

Unable to play BD-R or BD-RE discs in the Blu-ray Disc® (BD) player. Solution
The Blu-ray Disc® (BD) player does not support BD-R and BD-RE discs right out of the box. However, a free firmware update is available that will provide compatibility with BD-R and BD-RE discs recorded in the BDMV format.
If your computer is equipped with a DVD burner and compatible burning software, you can download the update from the Drivers & Software section of the Sony® eSupport Web site and then burn your own update disc on a DVD-R or DVD-RW disc. If you do not have the capability of downloading and burning your own firmware update disc, you can register the BD player online at http://www.productregistration.sony.com/ and a firmware disc will be sent to you automatically; the shipping and receiving time for the disc is approximately 7-10 days via U.S. mail.
NOTES:

• The firmware upgrade does not support BD-R and BD-RE discs recorded in the BDAV format.
• Disc may not be played due to inadequate recording capability of the recording device.
• Disc may not be played due to a disc being in poor condition.

I suggest that you install the latest firmware update to resolve the issue. Please click the following link to download the latest firmware update.
http://esupport.sony.com/US/perl/swu-download.pl?upd_id=6170&mdl=BDPS300
It is recommended to use CD -R disc to create the firmware update disc.

I hope you're clear with downloading the update from support page.

Once you download and save the file in the folder in the computer, you can double click the file to extract.

You will be prompted to save the UPDATE_BDPS300_VER0550.ISO file in a folder.

Most of the customers will be making mistake here after...

We need to use a burning software which is capable to burning discs from ISO images. ISO image is nothing but a RAW format of burned image.

I will give you the instructions to burn using Nero.. Steps will be almost same in all ISO capable software.

Open installed nero software from computer. You may locate it under Start Menu programs. Go to File Menu (Some times you will get a wizard where you can select the Image Burning option or burn ISO option)

Navigate the extracted .ISO file we saved in the computer.

follow the onscreen instructions.

Insert the disc when ever Nero asked to insert

Hope this helps. If you need any assistance. Please get back to me. I will be more than happy to assist you. Thanks for understanding.
