I am running Windows 7 with Virtual Box (current Version) and I have install a Ubuntu Ultimate version 3.2 as a Virtual Machine. All is well except for my attempts to create DVD's from AVI files. The system doesn't show that I have a DVD writer. Using K3B it doesn't show that a writer is in the system. I have also tried DeeVeDee software as well and it also doesn't see the writing capabilities. If anyone can direct me to the area of this problem I would greatly appreciate it. Is this a Ubuntu system problem or configuration of software packages? Thanks in advance.

My base OS is windows 7 and I installed virtual box on top of that. my Ubuntu Ultimate 3.2 is running within the virtual box as a guest. any other thoughts.. i will gladly take.

What exactly is the problem with devede? I just created a DVD yesterday from avi files on Ubuntu11.04. You can create an iso image with devede and run it in vlc or whatever movie player you are using as well as burn it to disk with k3b or other software. I'd suggest googling for some tutorials on devede. I just started using devede two days ago and one of the things I was able to do was create a DVD from AVI files. More specifics on your point of failure would help. Here's a link to one. I can't seem to find the one I used. I'll post a link to it if I do.

Regardless of the operating systems the linked page shows how to get a DVD writer visible as such to the guest OS -- I thought that was your problem?

I think it the OP has two problems, not having a DVD writer visible and not being able to create a movie DVD from AVI files which should not be that difficult with devede. Once he has done that he would still need to burn the image and your link should help with that but there isn't much detail in his posts on what he has tried or what has failed?

Thanks guys for all your continued help... I have found out that there is something I needed to adjust, due to the system I am using. In virtual box I did not have the Drives mapped correctly. It gives an option to select Pri-Master, Pri-Slave, Secondary master and slave. I did not have them selected properly and therefore the the pass-through option wasn't actually enabled. I selected that both of my DVD writers (Same brand and style) are now pointing to secondary master and slave. Both now have pass-through selected and both are showing in
K3B correctly as DVD writers. I am now ready to attempt some movies. The main goal has always been to take either AVI or MPG files and make DVD's that can play in my DVD player. Is DeeVeDee the best option for easiest making. I guess this is an issue with having a SATA system and not EIDE.

Don't know if it the best as i haven't tried many others. I'd never done it before and devede worked well for me. I guess it's a matter of opinion but I would check out some tutorials and all the options when you start devede to understand what it is doing.
