Hi Mark, I am sorry for my uncouth "broken". It was only for me "not usable" Your improvements on the sort command really look very promising. Thank you for caring about it!
The reason, why I can't use the AVFoundation is very specific to my environment. All of our products are based on a set of 20000 sign language videos, which were compressed and encoded 7 years ago with Sorenson squeeze. Though the codec was a h.264, Sorenson put its own name "Sorenson Video 3" into the header of the videos, which isn't accepted by AVFoundation and so the videos can't be played by the AVFoundation player. Getting all native videos out of the archive cutting and recompressing with a new codec has to be done one day, but is actually a real big deal for us. And I can't update the program anymore at the existing customer base, without exchanging all videos (8GB), what isn't realistic as an update. I would have to release a complete new version. And "if" I am heading this big task, it makes only sense, if I am sure I can use the new videos also with a new LC video player on Windows. So not being able to use AVFoundation isn't a technical issue, "only" an organizational issue in our specific situation.

I do think that 'completely broken' is perhaps not quite the correct phrase to use in this instance (I appreciate your native language is not English!). I believe 7.0's 'sort international' functions entirely correctly - it just does it substantially slower than before! I recently did some work on the sort command for LiveCode 8 to optimize it's performance: https://github.com/livecode/livecode/pull/2496 The improvements were dramatic. Indeed, the new approach is actually much better than it was prior to 7.0 as it ensures it only computes certain information it needs once, and operates on a much smaller intermediate representation. I asked Seb to take some timings of the stack you provided in different versions. Here is what he found: 6.7.7-rc-2 xSortListe 56ms - sort full list 6.7.7-rc-2 xSortListe 27ms - sort list items with 'a' 7.1.0-rc-3 xSortListe 596ms - sort full list 7.1.0-rc-3 xSortListe 293ms - sort list items with 'a' 8.0.0-dp-5 xSortListe 44ms - sort full list 8.0.0-dp-5 xSortListe 26ms - sort list items with 'a' So, I think we can hopefully say that sort has returned to its previous levels of performance (and indeed, might even be faster than before although the margin for error in the above tests is too small to say for sure) :) We'll look into back-porting this particular patch to the 7.x branch - the reason I put it into 8.0 was mainly because I was being conservative. If my changes were to break something, we'd have more time to sort it out on the develop branch, rather than on the 7.x maintenance branch. On an unrelated note... Can you explain why you can't use AVFoundation? Sorry to have to be the bearer of bad news here, but anybody who is currently dependent on QuickTime in any fashion is going to run into significant and insoluble problems as time moves forward. We have just about managed to preserve existing player / multimedia functionality in the Mac engine with the move to Cocoa (with considerably difficulty, I might add); but the reality is that we cannot continue to support QuickTime indefinitely as Apple dropped support for it, and stopped maintaining it several years ago. It could disappear from a new version of OS X at any point - it is already barred from the Mac AppStore.
