Burning DVD-R - how close to the disc's capacity should I go -

Hi folks,

I've been using Easy CD-DA Extractor (http://www.poikosoft.com/) to rip my CD's to the *.mp3 format and I'm wondering how close to the stated capacity of 4.7GB can I safely burn to a blank DVD. The file size of my collection currently stands at 4.61 GB (809 tracks/63 Albums - ripped at CD quality)
Is this OK or is it too much to burn to one disc? How much space is required(if any) for a table of contents?

I realise that the cost of experimenting with a blank disc is negligible but I'm curious all the same. Thanks for your help. Happy coding.

Regards,
