How much does a DVDR/W fit? Is it 4.7GB or 4.38GB? 8.54 GB or 7.95 GB? The DVD sizes can be a bit confusing. But we can be sure that DVD needs more space than any other video formats.So,if you don't have enough space to work with,you can use some tools ,such as imtoo video converter,to convert between DVD and other formats , There are basicly 4 different dvd sizes, DVD-5, holds around 4 700 000 000 bytes and that is 4.37GB.

Other non-standard special DVD formats: DVD-VCD - is basicly a VCD authored on a DVDR/W. DVD supports the VCD resolution but the audio has to be resampled to 48 khz. If the audio is resampled to 48 khz it is standard DVD-Video. DVD-SVCD - is basicly a SVCD authored on a DVDR/W. DVD do not supports the SVCD resolution but it may anyway work and the audio has to be resampled to 48 khz like the DVD-VCD. DVD-MP3 - is MP3s burned on a DVDR/W but very few MP3 capable standalone DVD Players supports it because most Players verify DVDR/W as DVD-Video only. DVD-ISO - is MPEG,MPG,VOB files burned on a DVDR/W without any DVD Authoring (making the vob,ifo files) but very few standalone DVD Players supports it because most Players verify DVDR/W as DVD-Video only.
