Here's a comparison of the AOS times for ISAT. (In HRD Sat Track, the duration is shown below the chart.)
I don't see a problem with any of the pass comparisons I've made between HRD SatTrack and the AMSAT data.
The real problem I'm looking at is related to rig control (specific to uplink Doppler frequency calcs) at the moment.
It's worth pointing out that (a) I'm using an HRD build that was generated yesterday and (b) some of you may be using an HRD build that was generated in 2012... or at least quite some time ago.

Mike, I don't see any times listed for the Amsat tracking. I think the problem is people are saying that HRD "lags" (ie, the track is correct, but several seconds/minutes behind). Regardless of if that is true or not, what I would suggest to verify HRD's tracking is to open two windows, one with AO-91 or 92 in HRD (realtime, during an actual pass), and one with Amsat Argentina's website:
Be sure to enter your correct grid square and select the correct satellite, and it will tell you current Az/El and doppler frequencies for Uplink and Downlink. I've found this site to be very reliable, and no installs are required (it runs in the browser).
Regarding the control of two VFOs simultaneously... we're working on this next. On another note, I've been comparing satellite passes between HRD Satellite Tracking and AMSAT's tracking and I am unable to find any differences. Here's an example with AO-91: http://www.hamradiodeluxe.com/AO-91-Pass-min.png
