Sony TRV 900 Questions

[Steve Robertson]

Two questions:

I recently purchased a memory card for my TRV900- so I could shoot 
stills without using the tape. When shooting stills with the tape, I 
could see a big difference between stills shot with progressive scan 
and those without progressive scan. The stills captured to memory look 
much better than the ones captured on tape. I'm wondering if the 
setting for progressive scan in the camera menu has any effect on 
stills captured to memory?

I'm also wondering about head cleaning. Do mini-DV head cleaning tapes 
do a good job? Is it important to use a Sony head cleaning tape? Or is 
there something better out there?
