A portable DVD player makes a great external photo viewer on location

I forgot the name of the guest the Light Source podcast team had on their show, but he mentioned a great trick.

Bring a sub-$100 portable DVD player to a location shoot, plug your DSLR into it using the video cable, and voila, you have a bright 7" viewer for your photos to check histograms, colors and sharpness.

Genius!

I guess you can also play DVDs on it when not shooting.
