Question DVD video recording at random place & time questions


I知 a newbie for Linux and Video. I知 trying to stream mpeg video DVD at random place, random time, just like Sony DVR camcorder can record video on DVDs.

Andy mentioned that with -use-the-force-luke=seek:N and 忙 /dev/dvd=/dev/fd/0 I should be able to record real-time stream from arbitrary location on DVD-RW restricted rewrite mode media. So I think I should get something like this to work

1. Create an empty UDF file system with VTS dir VIDEO_TS and so on.
2. Record raw video at random time, and mpeg encoding
3. Mplex to multiplex Audio/Video to mpg
4. Somehow dvdauthor to stdout instead of any directory under 電vdauthor 撲 option.
5. Then feed this stdout to growisofs 勃se-the-force-luke=seek:N 忙 /dev/dvd-/dev/fd/0
6. Somehow finalize dvdauthor 傍 to DVD media

Step 2 and 3 is as same as copy a DVD, but I have several questions for the other steps as follows,
1. Since I知 a newbie, anyone knows how to create an empty UDF file system with VTS dir VIDEO_TS and so on?
2. When using dvdauthor, -o option has to be a temporary directory, is it a way to get out to /dev/stdout or something, so I can feed it to growisofs?
3. In growisofs, what format I should have for 哲 in seek:N? For example, I want to skip the VIDEO_TS.* until the end, where I suppose to start for value N?
4. Is dvdauthor痴 VMGM should be recorded under the beginning sector of DVD?

I understand that I知 a newbie for Linux, UDF file system, and DVD as well. So I壇 appreciate if you could help me with any of the questions I posted here. Thanks a bunch, Chen
