DVD burning question!

Hey guys.
I'm using NeroVision to create a movie DVD that will be played on my DVD player. I've done it before with one 700MB .AVI file and the quality and playback were flawless.

Now, since the DVD i want to use can hold up to 4.7GB's, i can burn about 6 700MB .AVI files. So my question is, will burning all 6 of these files severely decrease the videos quality since NeroVision has to compress all these files onto one disc?

Thanks
 
There may be somebody better suited to answer this question, but my understanding is that Nero is not going to decrease the quality of the movie "to fit more." Nero will simply inform you if you put too many movies on the disc (aka reached disc capacity). Also, when Nero Vision converts the avi to be a DVD readable format, it will certainly increase the size, you may not be able to fit all six.

I'd bet if you were to look at the bottom of the burned disc you would see that the whole disc space was not burned. I'm sure your movie was not "perfect" quality but the quality decrease was simply not noticable to you.
 
Yes actually i didn't notice that before. I just tried to add only 3 and i already got a warning message!
So now, would burning 2 .AVI's decrease the quality? From what you've wrote Fred it wouldn't but i'm a bit stubborn for only one reason :x:: When converting a DVD to an AVI file, the default conversion size is 700MB. Of course, you can always adjust it to more if you'd like. This is why i previously thought only 1 .AVI file would fit with maximum quality.
 
The problem with Nero is that it uses the DVD standards of DVD recorders like SP, LP, EP to fit on the DVD. But a proper DVD encoding program would apply compression, so that it just fits on the DVD. But for example, a movie recorded in LP is only half the size of SP, but then also lowering the quality with 50%.

Back in the days when I used Windows, I was using the program ConvertXtoDVD to make a DVD out of video files. And I was really satisfied with that one :)
But if you have a DivX player, you could use AVI's in DivX or Xvid format and burn them to a disc as regular files.
 
how do you plan on playing the backuped movies, could i suggest buying a DivX compatible DVD player & for playback on a Win box look @ divx.com

Edit: with DivX you just burn as many .avi's as will fit on the CD / DVD / DL - you just chuck em on a disk

Edit: personally i'd bin nero & use the freeware burner CDBurnerXP

I think there is a slight misunderstanding here. You are not burning the films as they are onto a data disk. Nero is taking each of the films as a stream and converts them (encoding) to a DVD compatable video (MPEG-2) and then uses the new format to create a DVD movie type file system which can be read by your standard DVD player.

Yes, there are some DVD players which can playback Divx or other file formats which use the .avi container. If you had one of those then, yes you could fit upto (very roughly) 4700MB of movies in their AVI form.

Otherwise, Nero will give you a potential projection of your final project after encoding. It is a bit like blowing balloons into a container of set size. If you blow up one balloon it will take some or all the container. If you tried to blow up more balloons, they will all have to take less space, thus decreasing their quality, unless you like small squeezed wrinkly balloons...
 
thanks guys ;)
the dvd im burning is for a friend, she has a standard DVD player. I have a Divx DVD player though (excellent!).

I think i understand better the situation ;) thanks all
