What is M1, M2 record modes + question 120/240 DVD

[Troels]

Hi there
Maybe a dumb question, but is M1 and M2 the time you can record on a DVD ?
So M1 is 1 hour
M2 is 2 hour
M2x is 2,5 hour
M3 = 3 hour
M4 = 4 hour
M6 = 6 hour

What is the difference in using
4,7Gb 120M DVD and 4,7Gb 240M DVD

I am using a Philips DVDR 70

Yes.

Nothing. Notice that both of them are 4.7GB. It means that a 4.7GB disc can hold 120 mins in M2 mode or 240 mins in M4 mode. Think of it this way: a T120 VHS tape can hold 2 hours in SP mode or 6 hours in EP mode.
