Just done a quick google and couldnt find an answer to this - how many minutes of video would a 4.7gb DVD disc be capable of holding?
Not going to be played on a divx dvdplayer, just a bog standard one.

Thanks
 
Well I've got batches of Verbatim single and double layer discs. The single layers state 4.7GB/120 minutes and the double layers state 8.5GB/240 minutes.

Of course as Spleenus says this could well vary depending on the video's bitrate and whether it's stereo sound, AC3, etc.
 
As I understandand it 1hr on Ultra High quality, 2hrs high quality. You can compress it down further (if you've got something like a DVD recorder) to fit more on with obviously less quality as a result.
 
riteo, theyll be encodes of the standard quality divx files floating around which is lower quality than the standard dvd video encode, though I was thinking this wont matter as the files will have to be re-encoded back to normal dvd-video to play on the dvd player =(
Whats the deal with dvd-players and dual-layer discs? do most of them do it, or is it a special feature of certain models(i dont use dvd players, iv always had my pc as a media centre)?
Ill need to find the model number etc still from the person who the discs will be for mind..
 
dvd players should play dual layer media fine as almost all comercial dvds around today are dual layer
 
It all depends on the quality you want.
I have a Pioneer that will put 12 hours onto a DVD but its quite poor.
The 'standard' is 2 hours.
 
All DVD players can play commercial dual layer, as probably about half the films sold on the format are dual layer. I assume this means they are fine with dual layer DVDRs as well, although I've not tested it.

I suspect its the + and - thats more likely to catch you out. To clarify in case you don't know, there are two different types of DVDRs you can buy, +R and -R. There are also DVD Ram disks, but these are more or less dead. Many DVD players sold now can handle any of the formats, but some can only handle 1 or 2 of them, and in these cases, you need to buy the right media.

I'm trying to work out from the above statement wether you are expecting poor quality DivX files to improve to DVD quality because you have put them onto a DVD. If you are, then they won't and they may in fact get slightly worse.
