240 minutes on a 4.7 GB DVD-R?

Our Sony video camera can record 60 minutes on a 30-minute 1.4 GB DVD-R at reduced quality, and these "double-density, half-quality" DVDs can be played anywhere, including on our Mac. We would like to combine three or four of these onto a 120-minute 4.7 GB DVD-R, and burn it on our Mac. Is there any way to, or any app which can do this? It seems like there should be a simple setting or a check box. So far I've tried StreamClip, iMovie and iDVD, but I haven't figured out how to get this double density, if it's possible. Thanks.

iDVD allows only a maximum of 120min per single-layer dvd-r... (for good reasons)

a much higher compression rate is only accomplished with other, more elaborated tools as DVDSP/Compressor (=$$$$), or a tool for 23.32$, called VisualHub, it claims to pressssss up to 18h on a disk... ok, don't ask for pic quality 😉

another problem you will stumble into:
these DVDcorders use ...ehm DVDs as media; that is an end-of-the-road format, not intentionally meant for further processing; there's a lot of conversion needed, to make such disks editable.. and to squeeze 240min of its content onto a sl dvd-r is... such a project.- don't forget. the content on a dvd is not as on an analogue tape, you need a lot of mathematics just for playback.-

for a beginner, I recommend VisualHub...

Karsten, vielen dank, VisualHub is exactly what I was looking for. v1.1.3 was just released, and is a little buggy, but it gets the job done.
