Is there a point at which too many of these errors will make a noticable impact on the viewing experience? What do the more experienced people do when they come across these errors in a movie they're reauthoring?
From personal experience, you want to look mostly at the size / duration of the errors. ie. If the errors only account for small blocks of data, or brief moments of time, then you might find that the repair process adds new issues (or more importantly, the actual logged errors are not at all noticable on viewing).
Generally I do not use the Repair option of Mpeg2Repair. Someone suggested that you could "log and repair" at the same time (if you have sufficient disc space), but then, how much time do you want to spend determining whether the "repaired" or unrepaired .TS is the best to use for he HD DVD? You would probably have to burn both to discs and view both, to determine which gives the best result (if indeed you could detect any difference in most cases)!
Personally, I simply "log only" via Mpeg2Repair, and unless there are significant timestamp gaps (in which case I run through quickstream fix), I just proceed with the HD DVD as is!
So far this has produced a visually error free viewing experience in almost every HD DVD disc I have mastered, with the exception of only 1 or 2 discs that had significantly worse errors in the Mpeg stream.
Don't forget that the HD-A1 is a pretty forgiving MPEG decoder (in fact in my experience it handles Mpeg errors as well as (perhaps better) than my HTPC. This is probably due to the fact that the HD-A1 is of course based on PC technology, but with a dedicated (and robust) OS / application software configuration.
