I am moving towards more HD content in my library. I've noticed an issue with 720p tracks (especially the daily ones from PO HD Hits).
System spec:
Processor 2.7 GHz Intel Core i7
Memory 8 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 650M 1024 MB
Software Mac OS X Lion 10.7.4
OS X and SSL are fed off the main 1TB internal drive.
I've scrubbed a lot of the info Promo Only uses in their files. I pretty much use Name/Artist/BPM/Year/Comment/Genre. The files are added to 2.3.3 with no issues, and report as analyzed correctly.
First time I play the track in the offline player though, it loads the track and the waveform slloooooooowly starts to display, always quicker at home when previewing than if I load it in the club and have something else playing already. If I let the track play all the way through it saves the waveform correctly so that I can see it properly next time. Here is info on one such track:

Here is a video I edited in 720p (tired of waiting for a US release), and overview always loads quickly and no writing on each ejection:

Now of course the BIGGEST difference I see on the surface is the fact the Cheryl Cole video is NOT writing the overviews to the file and using *.ovb and *.xml file instead.
Could the write on eject just not be as noticeable because it's doing a quick write to these files INSTEAD of saving it to the file?
The biggest worry is when switching around HD files a lot you have a few "oh shit" moments when you think everything is going to pause and drop out.
