Back and forth to D-Sub, as in, analog VGA? If so, you're basically using the analog VGA compatible part of DVI there, and you're converting that to HDMI then. The conversion might also change some of the timings during these conversions, hence "fixing" it for your recorder. Also, it's roughly the same as recording from analog VGA then.
Might solve the problem in your particular use case, but it's not a solution I'd advise in general. :)
