Looking for any recommendations for software that will allow me to take TV video recordings from DVD-RAM discs, edit them a bit and then write them to a DVD-R/RW format disc? This need has been prompted simply because I have recently purchased a DVD recorder for the first time and am now realising the drawbacks of recording on to my preferred media for this machine - DVD-RAM discs... The machine does not have on-board hard-drive but in all other respects representated better value for money. RAM discs allow me some of the flexibility of recording to hard-drive in the sense that I can edit the disc in the machine itself to some degree and also watch a recording on the disc while machine is recording another program to the SAME disc - so quite clever! Unfortunately I come unstuck when want to watch the recording on another DVD player - in a nutshell - not possible for most other machines.
Is there any particular authoring software out there that anyone might recommend? Am not looking for anything too sophisticated - just ability to edit out adverts etc, create DVD menu structure that is recognised by standard DVD players.
