Easy....
Here is a fast, cheap and easy way.
You do what I did. I bought one of those $30 dispoable camcorders at CVS stores, which only record 30 mins of footage and film yourself.
I did the same thing for my drum solo DVD "Stick to your stix" and people love it!! I rented some studio time at my friend rehearsal studio and play drums solos on the drum kit while he recorded the footage of me playing. Then, after you are done. You take your camcorder with your footage on there back to the CVS store and pay another $20 for them to process your footage into a DVD for you.
So, in total. It only cost me about $50 to produce my own drum DVD, which I still pass out to people with my CDs.
Remember, those CVS camcorders are a 1 time use only thing. That's all. so make sure you get the good stuff on there.
Also, If you want a more permanent Camcorder. Try Target stores and get the small RCA 60 footage camcorder for like $130. they are small and give about 60 mins of footage. Good luck
