Home Recording Disc Copy

[micknicho]

I have a Conia MR910d and when I record something for my home use and try to backup this recording using either Roxio Easy Media Creator or DVD Shrink 3.2 it comes up with an error message. This is the one for DVD Shrink "Data Error (cyclic redundancy check). Can anyone give me some advice please?

A CRC error during burning means one of two things - either the particular blank DVD you're using has been damaged in some way, or the DVD media that you have purchased is of a relatively low quality and your burner is struggling to write data to it.

Given you seem to have tried a few times, I'm guessing this has happened with multiple discs, and as such is most likely due to the DVDs that you're using.

There are really only two options - purchase different media, or pick yourself up another DVD writer which is more forgiving of low quality media. I had a number of discs that I could never write to until I got a new (AOpen) burner, which didn't seem to mind burning to them (the old Sony burner hated them).

Realistically though, given the price of a burner vs a DVD, changing your media is the more sensible option. Always a good idea to buy 1 or 2 discs of a particular brand the first time and see if your burner likes them, before investing in a spindle of 100 which may not work well with your drive.

Thanks Mate,

My burner is a LG and I am using Strathfield 8x -R blanks to originally record to and then to copy down to. I will try recording on a 4x -R disc and see if that is any different. I say this because I have been able to back-up other stuff I have recorded prior to using this Conia Recorder with no prblems (an older Panasonic I must admit) but it has now gone to the recorders heaven as it cost an arm and a leg to repair when it broke down.

Not familiar with your model but if it records in VR mode you will get the CRC error message anytime you try to copy a disc that you have recorded more than one session on.

Dont know how to explain it but I have found that once I record something on DVD using the Conia DVD Recorder, as previously stated I cannot back up the recorded disc, however if I back up the recorded disc to a video tape and then burn it down again to a DVD disc I can back up the 2nd dvd disc without any problems. Straing.

That is strange - and would seem to discount my original thought that it was something to do with the media. It would seem that if you can burn normally, but can't back up an existing disc, that the CRC error is occurring during the reading of the DVD, not during the writing of the new DVD.

Seems very strange that the Recorder would have trouble reading its own discs though. I take it you can play the discs without trouble using the Recorder?

I probably didn't explain myself properly in the 1st place so here is the full bit:

I plug my video camera into the Conia DVD recorder which is attached to my TV and copy my tape down onto a 8X blank dvd disc. I then finalise the disc so it can play on other machines.

I then go to my "puta" and put the recorded disc into my LG DVD burner, load DVD Shrink and hit open disc and it comes up with the message "failed to read Data Error (cyclic redundancy check). I then open Roxio Easy Media Creator and hit disc copy and it will come up with an error message telling me it cant read the disc.

I then take the disc out and place it into my son's (the one who still lives with us) DVD/VHS Combo recorder and I can copy the recorded disc down onto a VHS tape and I can reload the VHS tape back up and copy it back down onto a blank 8X DVD disc, using the DVDVHS Combo and it copies ok.

I can then take the 2nd disc I have burnt and place it back into the LG burner and it backs up without any problems. It is only the disc that is originally burnt using the Conia Recorder that I have the problem with.

Ok for those who want to know, I have 3 boys with families scattered around Australia and we like to keep each other in touch by sharing our home recorded media and store it for posterity.

As I said, strange

Does the Conia support recording to +RW media? If it does can you try doing the same thing and post the result, (no need to finalise +RW discs) all other steps should be the same though.

Ok, so basically you're finding that any disc burnt using the Conia Recorder is unplayable in your LG burner.

My first suggestion would still be the same then - try changing the media. A different brand of blank disc may just rectify whatever strange series of events is confusing the LG burner.

My second suggestion would be to try burning at a lower speed from the Conia recorder, if that is an option. While some say that the "burn at lower speed" thing is a complete myth now that technology has improved, I still think it's worth a shot. Certainly nothing to lose!

My third suggestion would be to check for Firmware updates for your LG burner - always good to make sure you're on the latest version in case LG have encountered and fixed this problem in the past. Or post your exact LG model and someone here can help look for it.

My fourth suggestion is to do whatever jok11n says, since he undoubtedly has better and more informed ideas than I do!

Any idea has the potential to be a good idea, you come up with plenty, I have found in the past that -R media prepared in a DVD recorder can be a problem for some PC DVD burners, it's a bit hit and miss and there are lots of variables, for the recording described it is actually done in real time (1x) so burning slower isn't really a valid option, even if it were an option (recording speed is not selectable on a DVD recorder anyway) You did remind me of something else though, because it's 1x recording only the Conia was probably designed around DVD V1.0 spec (1x and 2x media) 8x media comes under the DVD V2.0 spec and may be contributing to the non compliance, 1x and 2x media is hard to find but 4x media is often a safer bet in DVD recorders, trying some other media may get around the issue

The small Instruction manual that comes with the recorder states:
Compatible discs DVD+.-R, DVD, CD, Mp3, DVD+-RW, CD-R, CD-RW
Recordable Disc Format DVD+-RW, DVR+-R

The booklet says Finalise (only DVD+-R) and if a DVD +-R has been finalised, you can not record or edit the disc any more. If you want to make your disc compatible with another DVD player, you should go on Finalise operation. Does this mean that should I record on a DVD +-RW it can not be played on another DVD unless it has been finalised as well? I know I am confused but at 70 years young I am still trying to keep abreast of the technology of today as it progresses (god I have only recently learned to call it a radio instead of a wireless, as it was in my days).

lol - no worries Mick, you seem to be doing a lot better than most people would be here!

"The booklet says Finalise (only DVD+-R)" - finalising is not an issue with +RW/-RW discs, only something you need to worry about with the write-once media.

I have some 4X blank discs which my wife uses so I will give one of those a try and see what happens as well. Thanks for your help.

THanks mate, will give it a try as soon as I can get out to buy some (read 1 until I am sure) .
