I purchased Lee Holden's older "get it all" pack used (minus the digestion one), back when that was about 10 DVDs vs. however many he's up to now. I've actually traded a bunch of them and got down to the ones I use the most, and I think you've picked some of his best stuff.
To give you an idea of my own experience, I had -
original 4 pack - Beginners, Stress, Low Back, Upper Back
next series - Flow Continues, Weight Loss, Seniors, Healthy Bones and Joints, 7 minutes of magic.
and eventually purchased - Deep Sleep
The first ones I got rid of were stress and beginners. I found the Flow Continues much more calming and enjoyable than either. Beginners bothered my feet for some strange reason, and I didn't find the stress one as stress reducing as Flow Continues or Low Back. I gave the Seniors one to my parents, and then tried it with them and wish I had my own copy
. It's really good, and incorporates some of the joint mobility stuff from Healthy Bones and Joints. I've kept that one so far, but don't use it much. 7 minutes of magic I used for the 14 minute long PM routine mostly. I found the 7 minute ones too rushed to be enjoyable, and the AM, with the cobra poses straight off the bat, and ab work, not pleasant for first thing in the morning. I ended up buying Deep Sleep, and with the 14 minute PM routine on there which I like far more, I'm now thinking of getting rid of 7 minutes of magic. Because the main deep sleep program is so focused on upper body, I ended up trading the original upper body one, because I found Deep Sleep worked better for me in that regard.
The only other Lee Holden I might suggest to you based on my own experiences is the Qi Gong for Seniors one. I also really enjoy the Water program on Matthew Cohen's Qi Gong Fire and Water DVD - it's very relaxing. Like you, I sometimes have difficulties following the breathing on yoga DVDs. Two VERY relaxing options which focus on breathing in an accessible way are Daniel Hickman's Yoga Beginnings (available from Fitnessorganica.com) and Eoin Finn's Pure and Simple Yoga (with the "tidal breath" option - there is a very consistent breathing sound cue - the whole practice is very even and measured since it was set to a metronome). You also might want to look into Max Strom's Learn to Breathe DVD. It has instruction and activities on improving the quality of your breathing and includes practices moving with the breath. It ends with meditation, and is extremely relaxing to me - I often do just the practices minus instruction immediately before bed.
