Ok I am not sure what you mean but I am no expert. The TVIX uses a sigma chipset which is said to not support flash. Realtek 1185 had no flash support but the 1186 does as used in the new Xtreamer Prodigy. If it was a software limitation then Realtek could program around it but they did not, released revised chipset instead.
My FV-1 has no problem playing flash videos and catch up tv and I understand it is Samsung based but my Geniatech cannot although I know they are working on it.
