I currently can record 4 hours on a DVD-R disc. This is from a camcorder to TV/DVR. If I hit 'eject' the disc finilizes.

I would like to record 2 hours at a time. Take the disc out of the DVR until I have time to record the other 2 hours. Which DVD disc do I use w/o overwriting the first 2 hours?

I would like to finilize the disc after it is full.

I have asked 5 clerks in various stores and gotten 5 different answers.
