SC-900 does not play CD's Burned from Computer

when burning a disc make sure the box is ticked to play on all formats and burn at the lowest speed for better results

Try cleaning the lazer lens in the Panasonic cd player. Dust can cause it not to read the disk.

Some players are like that! You need to experiment with different makes and speed settings when recording!

It depends what setting you used to burn the disc. Some will only play on certain players. Many people don't also have the right CODECS to play video files with their media players. But they can download CODEC packs from the internet for free.

Are the discs ones that you created (burned), someone else burned, or commercial discs? The message of disc not finalized usually appears when you put a CD or DVD from one unit into anther without closing (finalizing) the disc. The finalization step doesn't matter if the disc is being moved between computers with compatible OS versions (for example: XP through Windows 7). However, any other device will need this procedure completed.

Take the disc back to the unit (computer or other burner) where the disc was burned. If the computer uses Windows, put the disc in the optical drive. Open My Computer (Computer) depending on the OS by double left-clicking on the icon on the desktop. Right click on the optical drive and select Close Session.

If you created the CD on another machine, check the details for that device.

Note: you should double-check that the format that you burned to disc is compatible with this CD player. Not all models support MP3 files. On my own older CD player, I had to burn WAV files without gaps in a Disc At Once format to get the discs to play without skips.

I hope this helps.

(if the discs were commercial discs or have been finalized, I would expect a different error. In that case, I'd suspect a tracking problem and a "No Disc" error.)

Some laser assemblies will have trouble reading discs from a computer. TOC errors usually.

It;s possible that you may have left the disc open or re-writable. Check this first.
The settings will be located in the software you used to burn the disc. Easiest would be to start a new burn session and read the available settings throughout the window prompts. It may also be located in advanced settings, if you don't find it this way.

Most cd players do not repond to rewritable discs,I recommend you use a plain cd-r blank

I have had similar problems in the past - on one computer discs burned using nero were unreliable but using Windows Media Player they were fine and on other computers the Windows programme was useless and produced unreliable inconsistent results.

I suggest you experiment with different burning software and maybe suspect the drive you are using might be past it's best.
I have several cd players in my vehicles and around my home. Only a couple of them will play all the discs and most of them are very choosy and will only read premium price shop bought discs and it is a waste of time trying to play a discount store or freebie disc, or many of my computer burned discs.

I don't know what the differences are - maybe it is the software or the power of the laser burning the disc or the sensitivity of the reading laser, but there are many differences in there somewhere. The situation is very frustrating...

I don't know if I really find the solution but several burned discs I decide to burn a poor disc 8x instead my emtec 16x and voil'a the disc go on my SC-HT70. I suppose it doesn't support new type of discs with higher velocities even burned at a lower velocity (4x). If any one have another solution please let me know.
Also I know we can upgrade firmware of Panasonic but it can only be done by a technician and it's very expensive.
