Maximum MPEG file size that fits on 4.7GB DVD

What is the maximum MPG file size that will fit on a 4.7 GB DVD?

NO SHRINK -- NO ISO CUTS -- NO conversion to different formats.
NO compression, no shrinking, no splitting, no quality reduction.

Amazing that NO ONE has answered this as far as I can find on Google.

Given Roxio (which I use) or Nero and a direct, no-loss, no-shrink conversion from MPEG2 to the DVD format, how small does the MPG have to be?  I tried 4.1 GB, I tried 3.5 GB, and I tried 3.1 GB.  They would not fit.  Other people say they cannot even fit a 750MB MPG file onto a 4.7GB in DVD format.

The question is specific, I dont want it sidetracked on discussing drive, file or recording problems, or other programs, this is a question requiring a numerical answer -- the maximum GB size of an MPG2 file, that when converted to DVD, will fit on a 4.7GB DVD.

I will only award the answer to someone who has gone through this hassle, and knows the maximum size. Thank you, please only comment if you have done this and know the problem.  And if you say a 4.1 to 4.3 MPG will fit onto a 4.7 GB disc when converted to DVD format, you do NOT know what I am talking about.  Sorry....

GL -- This sounds exactly like the number I was looking for -- of course it would be less than the 3.15 GB it takes to fit 3 short movies without ads onto a DVD, so I will be wasting almost 1/3 of each disc.  That is typical of the DVD debacle.  I will test it and let you know.  Thank you VERY MUCH for this information.
Nope, that looks to be too high.  A 1.246 GB MPG expands to 2.75 GB according to Roxio, so two of them (total 2.5 GB) expands to 5.54 GB -- too much for a DVD.  This is absurd.  It means I can only fit ONE 1.2 GB movie onto a 4.7GB DVD???   What an insane waste of space.  I am checking Nero now .....
Nope Nero does the same.  The expansion RATIO is 1.8728 to 1, as best as I can determine.  This means for the realistic size of a DVD at 4.3 GB true size, the maximum MPG size is 2.25 GB.  Comments?

Interesting.  I'm going to have to run a few more tests.  I don't think this is as black and white as simple math.  I think some of this is definitely dependant on the software you're using and the writing technology of your drive.

Yes I noticed it was software dependant, but only to the extent Roxio forced a header of some 80 MB and you couldnt get rid of it.  Nero didnt, so its final size was slightly smaller -- but in the end, if there is NO shrinking at all, the final size should be the same.

BTW, I noticed the new Roxio - version 8 - calculates the right size but then recalculates it to just barely fit on a DVD, obviously using its own built in shrinking -- however, version 8 is way too slow to use, it is definitely bloat-ware.  

Please look at this other thread if you can help ...

Please see my comment above, and thank you both very much for contributing.  I think I have it nailed to about 2.1 to 2.2 depending on software.
