Question about Panasonic DMR-E20 DVD Recorder

2 Answers

Hi, I have two DMR-E20 Panasonic DVD recorders. Both have the same problem in that they will NOT record to a RAM disc or a DVD-R disc. I get the message that the disc is PROTECTED. I hav e used the remote to UNPROTECT the disc but then get a message that "DISC PROTECTION CANNOT BE CHANGED" or something similar (I am not in front of the TV/DMR-E20 as I type this). Called Panasonic, and all they could do or say is send it in for repair. I have used the UPO/DOWN arrow keys to set the machine back to FACTORY DEFAULT - it did not help. Is there a FIX for this problem? I thank everyone for any help they can give me - its just very frustrating. Jeff

    This does NOT answer the problem - it SUGGESTS this and that! I have a total of five of these DVD recorders - but - two of the records will not UNPROTECT the discs. The RAM disc is a PANASONIC - and they work just fine! I have tried about five different DVD-R discs, from the high end to the low end - these two recorders will not UNPROTECT the discs even though they are BLANK! I have taken the same Panasonice brand DVD RAM disc from one of these recorders and placed the disc in each one of the three working PANASONIC DMR-E20 and the disc RECORDS and PLAYS perfectly! I have even used the remote to PROTECT and UNPROTECT the very same disc in the working recorders and can record and play - BUT - when that very same disc is placed in the problem recorders, I get the "PROTECTED" error message. I mentioned to the Panasonic tech support that perhaps this problem could be solved with a "SECRET" number sequence using a remote - but - he said that he could not comment on that as he had never heard of it. I have used all FIVE remotes on these two problem units and still get the same result.

    Any further suggestions?

    Question - how can I get this problem, and its replies, in A RUNNING LIST, as in an email, where it is one continuous message instead of this broken up system?

    The problem has NOT been solved - all five of the PANASONIC DMR-E20s are the same - they were all manufactured during 2001 and 2002. All five work flawlessly in regard to playing a DVD or a RAM disc. It is just that TWO of these machines will not allow me to RECORD to a DVD RAM or a DVD-R which the machines are supposed to do, and have been doing for many years. I should add that this problem did NOT happen to the two machines AT THE SAME TIME, it happened over a three month period or longer, I just dont recall when the first recorder started to have this problem.

    These two recorders are, at this time, part of my set up for a home theatre system. I temporarilly connected one of the other recorders to this system and it WORKED WITHOUT A PROBLEM, so it is not with the home theatre system.

    Failing to get an answer that fixed the problem, I am just about to replace these two recorders with two others situated throughout my home as I use them only as "PLAYERS' in these two rooms, an office and the bedroom. The other three recorders are located in another bedroom, in my garage, and the last one is used in a "recording studio" next to my computer.

    The RAM discs are manufactured by PANASONIC and up to this problem, they have worked perfectly. The other DVD-Rs have been manufactured by - SONY, TDK, MEMOREX, OPTIMUM, along with some others - they have ranged from the top of the line, to the cheapest of the cheap, it does not matter, in these two recorders, I still get the same message - "DISC PROTECTION CANNOT BE CHANGED".

    You say that I could use my computer to "REFORMAT" the discs. How do I know that it will reformat the discs to DVD RAM format? What about the DVD-R discs, what would happen with those? Providing you feel that this would "fix" the problem, how do I go about it?

    I await your reply,

    Jeff Drinan

I have seen your problem up here and noone helping so I will try a few different ideas.We're going to try a few things systematically and see if we can get this issue resolved okay?First of all,are all 5 DVD recorders the same exact model numbers?I assume they are all Panasonic at least?Greg
Also,the discs which do not record,you could try formatting them in your computer to wipe them clean.

    If you have a DVD R/W in your computer,it will format them as a DVD/doesn't matter.Insert it into your DVd computer slot and click on it's drive name you have issued and click on format.If you don't have a DVD R/W in your computer,don't bother.Also,the home theatre should not have affected either one anyways.The only suggestion for now is have you cleaned the optical eyes with lens cleaner?If it does come down to repair vs. replace,an optical eye goes for at least $60 and repair centers have a minimum parts price markup of 20%.So yes,replace would be best.New warranty and all that jazz.As for the 2 not working,can you tell when they were made?There is usually a number imprinted either within an item number or something which has a 2-digit code to tell when it was made.Just please bear with me and I'll try to get this figured out for you.I used to work on many components such as this.Greg

HI, well to my mind, if two devices are doing the same thing, I tend to think that's it is NOT the device, but the media, or if not the media, then perhaps the desired action simply isn't available on that unit?.
Many many DVD recorders simply will NOT play, and record all types and brands of DVD's. Especially DVD RAM, along with certain types of DVD-R.
Usually what one needs to do is read the specifications and in there it will dictate exactly what type/brand of DVD is to be used.
Most often the best sort of DVD to use, is the DVD-R/W, from one of the Named brands.
I do not think you have an actual "Fault" and the only type of "Fault" that could cause this type of thing, would be the laser Assembly, and or the Quadrant Detector, however this would also manifest problems with "Other" DVD's as well? Which don't seem to be happening? So I would tend to think, about "Other' reasons as to why this is so before sending off the unit(s) for "Repair"
Below is your user manual.

    Failure to accept DvD Ram discs in a Panasonic DMR-E55 Recorder

    Possibilities are that the laser lens needs cleaning (use a proprietary cleaning disc) or that - as long as you are sure you have original manufacturers' discs and not fakes - the discs are scratched or dirty.

    Panasonic DMR E55 Won't record AT&T U-Verse programs!

    Make sure you only use the correct type of discs: DVD-RAM or DVD-R for recording and DVD-RAM, DVD-R, DVD-Video, DVD-Audio, Video CD, CD-Audio (CD-DA) and CD-R/RW (MP3, CD-DA, Video CD formatted discs) for playback.

    DVD-RAM disks are in plentiful supply on eBay, both new and used. Keep an eye open and you should pick them up, new, for less than £1 Sterling each!

    I am unclear, though, what you mean about recording to and from the VCR. The DMR-E55 doesn't have a VCR facility, just DVD.

    Panasonic DMR-E55 DVD Recorder Problem

    I have been told that panasonic now have a faster speed disc on sale to suit the newer dvd recorders that dmr-e55 cannot record on as they are too fast. You have to buy the slower speed ram discs to suit the dmr-e55.
