Yo-Yo Ma!
I know it is getting late to bring this up, with the very last DVD box coming out soon.
I have all (nearly), episodes on VHS since years, and have watched them many times. But since the DVD's started coming out I always stay away from the episodes that will be in the the next boxes. I never watch such eisodes on TV reruns either.
Then once I have the new box I restrict myself to no more than two episodes per day. And no extra material! Only when I am done with all epiosdes do I dig in to the extra stuff.
