Is it advisable to still frame image fr a dv? A friend was telling me that the resolution will be so bad unless I'm doing it just as a contact sheet. So it's not even worth giving it a shot to try n print it out as a normal photo size? Can anybody try n explain that to me, in terms of the resolution, pixel and all? Appreciate that.

You may get away with a small 4x5 print but it will be a little blocky.
Heres the info.
DV footage is 720x480 pixels. That is it there is now more information recorded to the tape than that.
Even todays smallest still cams will take pictures of at least 1024x768, and the reason you can do more is the Megapixel count on the camera. They are stuffing alot of pixeels into that small space so you can view the image larger or get a cleaner crisper picturre if you keep it small.
Video doesn't need that because of how a TV screen woks. So DV only records the exact amount of information to display properly on a TV screen. This keeps the data sizes down and makes it so the tapes can hold more information and easier to transfer to computers and such.
Bit of a Soap Box here
There is no substitute for having a camera for still shots, a video cam for Video so on and so fourth. You will have to lose quality somewhere once you start combining multiple features into the same device

I totally understand the fact abt no substitution for still camera image with video. That's why there's a difference between photo and video. I'm just been tight up in a position where I need to get some image out of a event somehow cos' my SLR failed on me and all my still photography images are gone. Thanks for the explanation Brianb. Appreciate it.

The color is also a lot worse, unless you have 3CCD camcorder.

Honestly I'm not too worry abt the color cos' I can always digitally fix that with the color channel in photoshop. More worry abt resolution since it were to be printed out.

to add brianbs post:
and video has just 72dpi, most printers have 150/300 and more…
the pixalation is defined by the standard of tv sets, precisley the tube of it. you can try some photoshop tricks (deinterlace - you loose another 50% of info, but it looks "sharper", gauss softener etc).
