Is there any way to grab the frames from media element like a video without feeling any delay? – WPF

I have to show the frames from a media element in an Image control like a video. I have tried to grab continues frames from media element using a timer and bind that bitmap to Image source. But when setting the scale as 1, it seems like frames are grabbing very slowly. And when reduce the scale to 0.3 or below, the grabbing is working very fast. but the quality of frame is reducing.
Is there any way to solve this?
In short, I want to display the frames from media element to an Image source without any delay and with original quality.

Can you use the asp.net membership provider in a windows application?

The Asp.Net membership provider has some clear uses in a web app. I am thinking about trying to leverage some of the features in a windows application (more specifically WPF). Does anyone know if it is possible to use the core features in a windows app? I am mostly just looking for it to create my database tables, and maintain users, roles, and profiles. I obviously do not need to use the built-in web controls (e.g. Login).
