Trying to put a somewhat positive spin on the comments above.

"There is no point in an explicit show if the video is shot mid distance and the video clip shows the dancer as a small speck on the taskbar ."

DB is fundementally the same product as VG. The models are shot from the same distance and should show at the same size. It is the content that is different, not the format.
With the new software (1.0.4.65) you should be able to zoom to approximately full screen. 1680x1050/1920x0180 scale to 140%. 1920x1200 scale to 160%.

"Also some of the DB clips seem quite old and of low quality ( eg Sandra Sanchez )"
The current shows on DB are shot and comparible quality to all but the most recent VG shows. Compare to 600 to 650 shows, but less than 655+ shows.

" - presumably they were shot with the old hardware but were too hot for VGHD at the time and have now been recycled for DB."
VGHD has never had dildos. VGHD has never had sound. In the case of Sandra Sanchez, clearly a different hair colour, dildos and sound. I believe all the content was shot specifically for DB.

As with VG, some of the models are explicit than others. Sometimes it is external buzzing, sometimes internal. With the duo some of the models have more chemistry, or are better actors than others, some are more two models on screen at the same time.

So DB offers something harder than the VG. For the most the quality is (or should be) on a par with VG shows shot late last year, early this year. The format is similar with the pole dance replaced with the electric toys. That is true for solo and duo. If you like duo, there is much more interaction with the models touching, sucking and playing with each other. Then there is sound with the regular moaning and groaning that helps avoid language barriers. To date, the few bits of conversation that I heard are all English (usually with a strong accent).

This is not intended as a criticism of the comments noted. I too tend to prefer the solo shows and consider an ongoing subscription at at less than 1$ per show (10$ per month getting 12 cards) better value than 2 tickets/2$. I too tend to prefer the shows less explicit, so why pay twice as much to get additional harder content?

I am not convinced that you should be put of waiting for positive feedback. Sign-up, read the comments on the shows and if a favourite of yours from VG appears then give her a go.
