I don't think anyone here will know that, but do you notice any different with your box? Does it acutally work now. Please post your findings as the patch might be rolling out it was suppose to be in november.
I had a RNG 200N but because of the problems with video flash, etc. I swapped it out with an older SA 8300 HDC which runs with no problems after the Guide conversion. The downside to the 8300 is less storage than the RNG 200N.
I'd like to hear from users if the problems with their RNG 200N's are resolved with the latest software/firmware update and if so I'd give it another try.
