Hey Jake,
1. Sorry to hear about that - I don't think anyone else has reported a similar issue regarding the recording. Does the problem occur with and without the DDJ-1000 connected?
2. The track re-ordering in a playlist is only possible when sorted by the order number. If you're sorted by song name, it can't change the order as it would break the sort.
3. It could be a bad fader - but first, check the setting for the cut-off lag in the rekordbox preferences.
4. You may have seen that if somehow you were logged-out of the rekordbox account. KUVO is the server that does two things; one, allows you to share your track titles when playing, and two, activates rekordbox. I'm glad it's gone away since you logged-in, if it becomes an issue again, let us know.
5. The latency is more likely to be due to your computer specs, background applications, and the audio buffer size. If you have any "performance booster" applications or graphics optimizers, please disable them. If you notice the latency getting worse, you can try opening the task manager to see what applications are running and consuming system resources. You could also try using a latency monitor.
6. See above, and if you're still having problems, please file an inquiry ticket here and our support team will gather some additional information to assist you in resolving this issue.
