I never used a DVD course in its entirety, but I do like Sporty's style from what I have seen. A few things that helped me:
As boring as it sounds, visual learner or not, read the 'Instrument Flying Handbook' (FAA-H-8083-15A), cover to cover. You will be glad you did once you start flying.

I would pick and choose certain things out of the 'Instrument Procedures Handbook.' That's a boring one, but practical and informative.

I still frequently reference 'Everything Explained for the Professional Pilot.' Clears up a lot of muck about the Regs, but then again it is still someones interpretation of them. None the less, I've yet to find any disagreements.
Written: Sheppards, Gleims second if you want more enrichment. Of the written exams I have taken, the Instrument was the most practical, so it would not hurt to get more in depth with the study here.
Read this every night:

A few things have poor explanation, but if it leads to more questions, great!
If you are flying with a 430/530 download the free emulator from Garmin's website. Avweb has a great tips an tricks video using the 430/530.
Get some fresh coffee and you're on your way.
