I tried watching this new cut as well and really didn't enjoy it. having both opening sequences didn't gel very well together
The TV version opening prologue has no place in any 'Lynch' inspired or approved edit IMHO. as far as i can recall, it was the TV Prologue that made him remove his name from the film
I do enjoying both versions of the film though. The theatrical version is amazing as it is (I'm quite a big fan of the film). The TV version is a mess but still interesting to watch. But combining the two just makes it a mess.
I'm in the middle of reviewing the latest Blu-ray from Germany (It has both cuts in HD) so looking forward to getting my observations written up (Extended version is a hybrid of HD and upscaled SD footage btw)
