NVE - big difference in version speed

Further to previous postings about all NVE versions taking much longer to transcode a video than v3.1.0.11. I now find that Nero 7 has the same problem, after an uninstall of v6 and using the general clean tool. A 1.5 hour film takes an hour loner with the later versions.

Even the fast initial ‘preparing to transcode’ bar takes much longer on the later versions.

I can reproduce this across 3 PCs and NVE is set up identically. Tests are run using the same video.

Has anybody any experience of this and know WTF is going on?
