I've noted with my 2012 Panasonic plasma (50ST50) that with various 3D titles in over/under format that my Time-Warner cable uses for their 3D titles (720p) and other sources, that a few times when the scene changes dramatically in the title that the plasma drops out of 3D mode.
This happens no matter what auto detect mode I select in the 3D settings (Off, Auto1, or Auto2) though Auto2 will correctly detect the over/under format correctly initially.
I've even tried manually selecting the over/under 3D format but it can still drop out of 3D mode a few times during a title like the plasma is still comparing the two halves of the picture even if the 3D setting auto detect is not set to Auto2.
This seems like the auto detection algorithm is a little off, maybe needs to be relaxed a bit since some scenes the two half images can be more varied in some transistion scenes?
Also it would be good if a manual 3D format is selected and Auto2 mode is not selected, that the plasma should stick in 3D mode with the selected input format and not drop out at any time, until manually switched back to 2D mode.
Is there a standard place to report such issues so Panasonic might put it on a list to be fixed in a future firmware update?
