Here's an interesting collaborative tutorial/interview with Denver's Dave Dugdale, the creator of the site Learning DSLR Video and James Drake, owner of the Denver RED rental facility 5k Insight. Drake covers the similarities and differences between shooting video with a DLSR and with the RED Epic, aiming his comments squarely at those who want to regularly transition between both cameras but also those who might need to intermix footage between the two.
The tutorial was shot by 5k Insight's Patrick Downey on a Canon T2i.
