about DVD s.lines and VHS 4&6 heads

hi all,

i have tentatively taken steps to convert VHS tapes to DVD, but need two questions answered before i can go ahead.

an s.line connects DVD to TV. what does it stand for, and how is it better than the three coloured cable i am currently using.

re: VHS. why is a 6 head player better than a 4 head. one person told me 6 head is better for editing. another told me it allows a better image quality.

i intend to transfer black and white films in mono, so would any of this matter?

thanks. some of you have been a great help in the past. much appreciated.

4 Heads are for mono VCR`s.
6 Heads are for stereo VCR`s.

Main ones are Erase, Record, Sound, Video, *IF* I recall my old electronics theory correctly (I didnt follow C & G224 Part II TV servicing, I took C & G 224 Part II Industrial Equipment Servicing - The first year you werent able to take both exams due to syllabus changes in 1985).

4 HEAD MACHINE.
Right, two heads for HI-fi sound.

Two heads are for picture,on a 4 head machine the 2 heads have to record in LP and SP speeds and of course play back as well,this is a compromise the heads are thinner and leave a gaurd band in SP mode but not in LP mode.

6 HEAD MACHINE.
2 For sound ( not used in mono machines)
2 For LP.
2 For SP.
No compromise.

A standard Nicam Stereo VCR has 4 heads on its drum - two for audio, two for video. 6-head means that the VCR has two extra video heads, to provide better image quality in search and pause modes. There`s no advantage to 6-head for normal recording and playback.

Mono VCRs lack the two audio heads, so a 4-head mono VCR is equivalent to a 6-head Nicam model.
