I decided not to buy any of them (for now).
If you set all movie releases from vhs and dvd next to eachother, you'll see that any title has been re-released many times by now. And during all these re-releases only the artwork has been changed. Very little to none work has gone into restoring the audio/video quality, adding surround sound, movie extra's like bloopers (yes, they do exist), or a small documentary about the particular movie with co-stars and other insiders, nothing...
ABout 'This Is Elvis': this documentary has been made in the early 80s when very little candid footage of Elvis existed. THe general knowledge of Elvis also was less than it is nowadays. We -the world- seem to understand the man behind the image better than in the early 80s. So why hasn't this 30-year-after year been used to re-edit This Is ELvis? New footage, different voice-overdubs, etc?
These last releases at least seem to have some improved audio/video quality. But I'm so fed up with the way the music and movie companies (and even EPE) treat the Elvisfans. If you think of it, it's still the same formula that Colonel Parker used.
I'll buy the HD-dvd's eventually.
