DVD +R disks

Post by **Ken Berry** » Sat Apr 29, 2006 11:43 am

Glad to see you too have experimented Helge. I failed to mention the Ritek discs I use regularly are 12x, but I continue to burn them at 4x, and have not suffered any problems. I continue to stand by that. But I have never experienced any difficulties either in trying to burn them at 1x speed either -- though I have never tried. I can select it, but don't.

>>>I seemed to have problems with Memorex DVD +R disks (4x - 8x).

Same here, I never use them.

Whilst on this subject how do members get on with RW disks?
I find that a brand new ones work perfectly but when you erase an RW disk they work but you get the odd blocky bits here and there. I get the impression that they dont erase fully.

Steve,
Somethimes I have to perform Full Eraser of the dvd-rw's which takes a good amount of time.

Never a problem in the stand alone dvd recorder (Sony).

I've never used the RW disks before. But I will be now. I just bought a DVR and to get the data out, I need to put it on DVD-R -RW or DVD-RAM (which I had nevere heard of before last week). Supposidly you can re-write the RAM disks 100,000 times. According to the book, it looks like I have to format them first. They also have a Tray that the fint into.

You most likely are using Panasonic trays (they are great).
Hitachi is similar and using the same patent from panasonic for dvd-ram.
Maxell and others make the cassette/trays to work in those units. The ones I have are removable by poping out a plastic pin in the cardtridge. Also have double-side ones that are very handy.

Using the Dvd-Rams in a computer is tricky with the dvd recorder.
Dvd-ram gets written in the DVD-VR mode. You can't use dvd-ram and try to write it as a dvd-video disk. Ulead and other programs will say unsupported format. You can write dvd folders as data folders.

You will need to read the doc's on the recorder. Many of the dvd recorders that write to ram will write to the dvd-rw disks in DVD-VIDEO mode with the VOB folders.
So, the dvd-ram is written only in Dvd-vr mode.
The dvd-rw will be written in Dvd-video mode.
Two different methods/formats, still are mpg2 dvd compliant files.
That gets confusing because on a Sony dvd recorder that writes to dvd-rw's you can write them in either the dvd-vr or the dvd-video mode.
Some units can write dvd-rw's in -VR format and some can't.
The difference between the -VR format and the dvd-video format is you can trim/cut/divide the video on the disk written in the -VR format.
The dvd-video mode you can only delete it and not edit it.

If it helps,
Sony just released a triple format burner that can read/write dvd-ram.
Maddog media can also read/write dvd-ram.
Some Lite-On units can read dvd-ram.

When using a dvd recorder dvd-ram is the fastest and easiest. Dvd-rw and dvd+rw's are used but are slower to process.

To protect my masterpieces I put a d_skin on them. They work great.

When I use those skins I was having trouble reading the outer layer of the dvd.

The cartridges referred to work in Panasonic dvd recorders.
I guess Hitachi also uses them.
They are hardplastic square with a door that slides to the side for access to
the dvd after insertiion. Dvd's are removable. Also a write-protect switch.

Why the industry never adopted them I don't know. They are the best.
Many people that own the Panasonic Dvd Recorders don't know these cartridges exist. If you look at the sides of the dvd tray there are 2 ledges (one on each side) that is made to fix the cartridge.

One would think the engineers would do this for the Blu-Ray disks.

Beware of TDK brand discs! They are (apparently) sometimes (??) manufactured by a third party (???) - CMG or CMO - something like that (I am at work at the moment and can't remember exactly). A local computer magazine article mentioned that they purchased TDK brand discs and experienced high error rates (they discovered this as part of a review of DVD burners) - they investigated further and found they were not manufactured by TDK at all! I have personal experience with this - I purchased at separate times, 2 spindles of 50 TDK discs - Nero information reports them as being manufactured by this CM? manufacturer rather than TDK (unless this is a TDK subsiduary). I have experienced error rates on the discs (I normally ask Nero to do a verification pass - the verification fails approximately 1 in every 3 discs). I am now at the point where I have decided to discard both spindles - unfortunately I did not keep the receipts, so I can't return them. This is over 80 DVD discs that I will be throwing away because I just can't trust that even after I get them to burn and verify correctly that the data will still be OK in the future!

So I would suggest staying clear of any TDK brand discs - unless the seller can guarantee they are manufactured by TDK - and even then keep your receipts

If you do decide to purchase then put one through Nero and verify the manufacturer before using any of them!

P.S. I never burn at more than 4X - doesn't matter which of my 3 burners I use (2 pioneers and 1 LG).

Have a look at the link below. The bottom line is that most of the time the Brand Name you see on the discs bears no relationship to the actual manufacturer of the discs.
Additionally a manufacturer like CMC Magnetics, referred to above, can turn out both absolute trash as well as high quality media depending on what the client is asking for. TDK manufacture some very good media themselves, but they also market, under their own name, media sourced from CMC Mag and others. Similarly I have Sony discs made by Sony as well as Sony discs made by Ritek. The only way to really tell is by using the Nero tools or similar program to identify the ACTUAL manufacturer.
I personally use weird brand name media that always ends up being CMC Mag AO1. I burn slow and careful at 4x speeed and end up with burns that score 95 using the Nero CD-DVD Speed benchmarking software that never give trouble so go figure!
