I just wondered how long between grabs you folks were using for your movie grabs?

In your opinion, is there an 'optimal' time setting that will work well irrespective of the length of the DVD?

Obviously im looking to get as much use as possible out of this DVD content but, at the same time, i want the screengrabs to be high quality but also not be full of 20 pics of a guy taking his shorts off LOL

Any help you folks can offer would be appreciated

Regards,

Lee
