Only 395%?
That's absolutely nothing compared to what I got! Mine showed as 1501688% and similar! Now that is a big percent, right?
I have been sucessfully running 1.22.384 and decided to update to current 1.31.437 a couple of days ago...bad mistake...
To test it out, I tried simply looking for any video files in my recycle bin...and my percent values showed as these enormous values...and...as OP said, my "time to complete" kept changing constantly also, varying from a few minutes up to 25+ days! Catching one of those high nbr day values was quite impossible so I just took what I could get, which was still a nbr of days, and is obviously wrong.

BTW, I'm on W2K here...and have reverted back to older vers for now...
