1.Can it do high speed dubbing of burned dvds to the hard drive, and reverse?

If yes, is this only for dvds burned on this recorder or can it do high speed dubbing to the hard drive of dvds recorded on other models?

2. Can you split/merge titles on the hard drive?

For example, if I record a 6 hour vhs tape to the hard drive, will I be able to split it into one hour segments later, and give each one an idividual title and chapter marks without too much of a hassle, and then high speed dub to dvd?

3. How finicky, if at all, is this model with blank dvd media?

And could people who own this model tell me what they think of the picture quality, please!

After some research, this is about the only model within my price range, and can play/burn +media.
