If you had three field, there would be people who "need" three fields.
(And if you had four field, than there would also be people who want all
four fields.)

IIRC that was MUCH earlier. But i could be wrong. I haven't suggest "much"
in the last month.

OK. I haven't read the manual. (At least not that part.)

Okay. I don't see the usefullnes because i'm one of the few people where
VDR has NEVER deleted a recording and will NEVER get the chance to do
that, so for me that feature is pointless/useless. (I move them away from
the 2 DVB-Computers to my "workstation", cut them, burn them, print a
Label on the CD-Rs and put them "away" into my "Archive-Wall" (1x2Meters,
35 Boxes for 80CDs each))

I won't ever get that problem. But i don't think thats "right(tm)"

Lets toss a dime, that would be fair for all. :-)))

(I take "head", (Head has "slightly" more mass, so the chance to win is a
little bit more than 50%))

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
