im planning on sale the xrgb3 and get the mini frame meister that will help ? please let me know
if you want to upgrade to the Mini, then yes, it will solve your problem.
With the XRGB-3 I had the same problem when I replaced my Sony XBR5 with a HX900. Adding a RGB interface in between (I have an Extron RGB 203 Rxi) did the trick and the XRGB-3 worked fine on the HX900 in B1. I would suspect that it would work on your setup as well. Cheaper Extron RGB interfaces like the 190 are available for $25-30 on ebay.com, so if you want to keep your XRGB-3 for now, give it a try.
