I have a 4hr and 30 min recording im putting on a dvd. I own a philips dvd recorder. Now my question is it has 6 speeds...1 is highquality, 2 is dvd quality and so on...now my question is the 4th speed is 4 hrs long and then the 5th speed is vhs super long play quality....which is 6hrs that i can record to a dvd. If i use the 5th speed since i have a 4.5 hr recording to do,will that downgrade the quality of the program when its recorded? my thought is a vhs tape is one quality and u cant improve it?
