    I start to record and get about 6 seconds into recording and it stops. It will play DVD's and record from DVD to VHS tapes. I just recorded from tape to DVD a few days ago. Ran out of the Maxell DVD+R brand I always use, bought more. When I put in the DVD, it says "The disc may be dirty, have an incompatible format, or region code." Bought Imation, the other suggested brand, it didn't work. Exchanged them for another unknown brand, they start to record, stop but no error message like before. Cleaned the lens, recycled by unplugging, read the manual front to back, need more help than I can do on my own. Suggestions?

    i finish recording a movie the other day and when i tried to stop it, the red stop light just continue to blink, then about 10 minutes later it came up disc error and when i tried re-inserting disk message "Disc contain unknown data" appears. Is there a way to recover from this? Also how do you recover a disc if there is a power outage during recording. I have lost alot of money throwing dvd's away because they refuse to play for me....Please help

    Receive disc error when recording. Disc is unreadable. I have noticed that i can record 1 hour of video but no more. I am very disappoint with this product. Magnavox will not help because the warranty has expired. This is obviously a design flaw.

    Can record/playback approximately 75% of disk, then will suddenly flash error message and stop. Only happens when I am recording or playing back a disk I have recorded.

    Started out freezing while playing a brand new purchased, prerecorded disk. I used a lens cleaner, as I had about 10+ hours of use. Still get freezing and skipping, now have additional problem as stated above. Sony RDR-VX525 is only about 6 months old - this is ridiculous!

    I had to replace the dvd drive assembly.Cost about 280.00 with shipping but working like new.

    courtdate - thank you, but that's what I am using and it's all I've used in the machine, other than prerecorded disks.

are you sure the drive is a read-writer? some optical drives are read only. If its not a writer and you put a blank in, that is what it would do.

If you put a real and recorded disk in(not a copy) and it says unknown disk, the eye is dirty. Cleaning the drive will be the next step.

Use lens cleaner disk to run many times. It cleans the lens and also runs cd on the disk which eventually will get rid of moisture on the circuits and restore your dvd recorder on the LG unit.

Error code E 4 54040990

You need to go into the set up menu and select recording options. On the recording options menu, scroll down to dubbing options. On the dubbing options menu select either VCR to DVD or DVD to VCR.
Recording and Dubbing are not the exactly the same thing. You use the record buttons to record TV directly to VCR/DVD you use the dubbing buttons and set up to record DVD to VCR or VCR to DVD.
Hope this helps.

Bush television & DVD error message 'unknown disk'

Some units jusy won't play certain types of recorded DVD discs. I would transfer one to a DVD+R type and see what happens. Buy a good brand like Memorex.

Hope that helps...

Unknown disc error

Either the lens of the DVD drive has got dirty, or the drive itself is faulty. Try cleaning the lens with a lens cleaning disk, if this does not work, return it for replacement (If it is still under warranty), or take it to a repair shop to have the DVD drive replaced.
