Problem after installing 1.5.2

I have a Samsung D series and a Samsung H series (48HU7500) and I had version 1.5 working fine.
Both Tvs were able to see online sources. And both of them were able to see recente mkv files that need trancoding. ex: High@5.1 coded
After upgrading to 1.5.2 my H series simply does not play online sources but my D series plays them.
Also my H series does not play ant transcoded movie error: check your network
Any ideas?
