Don't remember UR saying it but alot of people have, mainly because it only seems to effect certain TV's and also people using older UR images wouldn't have the issue as it was a bug created by UR, images from before last July "ish" didn't have the widescreen isuue.
i could NEVER replicate the issue on my tv, which is a Harwa 37" LCD. i then had a 22" samsung LCD and it showed on that, so different TVs are definatley something to do with it as well
ive attached another test image ive been playing with, its for the TM500Super and the TM600 if anyone wants to have a look, its still FTA (for now ) but ive triple checked the miniweb is ok for reflashing afterwards, as well as a few other things like telnet and web interface, if anyone wants to try it on the TM500, let me know and ill create and attach the image
if this image is fine, then the next step will be to work on things like cccam and download panels
