Unfortunately there was no change in any item that had been invariant with the cable unattached.
The bit could be in one of the varying digits, in that case the changing values should be different with/without the cable, e.g. it might cycle 1, 5 without the cable and 9, d with.

Don't forget what the H stands for.

The sig finder match I added last night says the video detect bit should be 0x00800000 in word 0 for this camera.

If the sig finder is correct then I should probably have just bought some toothpicks.

With no cable, the 3rd nibble (of word 0) includes 2 & a. However, it includes 2 with the cable connected.

I had (somehow) initially suspected a bit of the 5th nibble ... with no cable it included 1 & 5 while the first occurrence of that with cable connected was d. However, a second test with cable attached had that return 1.

Anyway, only if the sig finder is incorrect does there seem any purpose to analyze other changes but I wouldn't then be sure how to pin the bit down.

Screenshot and spreadsheet of results attached.
