I haven't been able to convince my system to lock up ever when using the bt. P133, ASUS T2P4, PCI IDE, SCSI, Ethernet, 40mb RAM, Mach64, WinCast. Still haven't gotten 24 bit color working right -- I'll send our notes out later. > In my case, it seems to be related to having fxtv's view window resized > to something between the default "small" size, and full size and having > a marginal input signal.

I know that bouncing the signal around (ie rapidly changing channels) will sometimes cause the tv to freeze, but changing it again resets it all. (I did this for the first time yesterday, changing channels a bit faster than my real televisions can do it!) > Also, as I've mentioned to Randall, I think that the even/odd fields are > interchanged.

Is it just me, or is anyone else > noticing this? That was me, I think. I suppose we could swap the even/odd reads and see if the image looks any different. I can check it by clicking over to the Weather Channel or watching ESPN or any matter of channels with lots of graphics. Oh, don't look at ME to do that.
