Neither has a fastidious benefit with accept to transferring record to you PC. Tape has the benefit of being replaceable with another cassette even as you're "in the field" shooting record. I don't know what you're held to do with a hard handbook camcorder once the handbook gets full.

The DVDs are compressed plot but you will not see much difference on a small TV if you equate it with miniDV. You can imagine, the file size for 17mins of DV is 4GB (Gigabytes) and for DVD 30mins = 1.4GB. So how much record is compressed, you lose the feature.

Similarly, I never would go for the hard handbook camcorders on any affect up. The record is greatly compressed. But yes you can also confirmation record in a DVD feature so a 20GB hard handbook camcorder can hold 4 hours of DVD feature record or 20 hours of poor qualilty record. What if you are on holidays for 10 days and you want to confirmation more than 4 hours? Can't confirmation more coz you are run out of disk interval.

Well my inclination:
DV is the best plot, feature and dependable. You can confirmation record to notebook and then burn high feature DVDs or confirmation record back to miniDV tape after control.

For DVD, i would say it is very simple to use, as once you confirmation record, it can be played directly on most DVD players. Note that I said "most" instead of "all". Some DVD players only help some type of DVD discs (+ and – R or RW).

I hope this helps.
Oh also, Hard handbook camcorder will never be included in my list.
