Thanks
The "no viewport data" seen on i980 and i860 are another one I've seen intermittently before. I think it happens when the camera is in play and there are no images, but only sometimes. It could also happen if the camera started with a video selected in playback, but I assume that's not the case on your cams.
Interestingly, the transfer speeds seem quite low, I'd expect a digic IV cam like Ixus 980 to be more like 30 MBs than ~5. What kind of system are you running these on?
If you want, you can include shoot=true, like
chdkptp -e"exec require'camtests'.runbatch{bench=true,xfersizebugs=true,shoot=true,filexfer=true}"
which will make the cam also switch to rec and test various shooting functions. Definitely no need to redo any cams you've already done with this.
