|Does the 24 hours include the time it takes to convert the video to a proper format?|
How are you getting the video from the camcorder to the hard drive?
What is the file extension of the video file, before burning?
What burning/converting software are you using?
If your video files are in a format other than .VOB, your burning software will attempt to convert the file, prior to writing to DVD. Conversion times vary, from one program to the next.
Try using a third-party conversion program to produce compliant .VOB files (the specs can be found on the net) and place them into their standard folder structure (TS_VIDEO & TS_AUDIO folders). Burn these two folders to a DVD, and I think you"ll find that the burn goes much quicker.
The freeware program "SUPER", doesn't make compliant .VOB files (maximum file size = 1,048,574 KB). Super will convert the file to a single .VOB file. Most burning software will reject these non-compliant files.
That's not to say that there isn't a problem with your burner. The error you get, when using DVD+R, seems to indicate a problem (assuming the burner actually supports both +R and -R).
