I have no way of knowing this. However, I think they are easily replaced by much cheaper USB alternatives today. I did some work on the zoran driver several years ago, but it doesn't use the vb2 framework (and not even the older vb1 framework!) so I'm sure there are all sorts of bugs in that driver. Personally I would be fine with moving this driver to staging and removing it by, say, the end of the year. Nobody is going to work on it and I think it is time to retire it. Regards, Hans
