This is a quick test to see if this DVR works in pass through mode. The test involves an ION VCR2PC with a tape in still frame. The result through the Ion was noisy, with flagging and jumping. The same signal put through the Himage at the same time (and captured simultaneously by another capture device), was quite stable but had a noise band in one field. I'd say that it's definitely working as a TBC.
Sorry for the low quality, the ION will preview but not capture in
VirtualDub. I can only play with graphedit or install the original software. I may make a better comparison sometime.
