I was having issues with my Actiontec (Verizon FiOS supplied) router... I suppose it wasn't multicast enabled or maybe it was NAT table but it would always disappear from XMB until I rebooted router.
Anyway, now I have a Linksys with DD-WRT and that problem is solved, but I suddenly have even low quality videos stuttering whereas before I had no issues (even 720p MKVs were streaming fine over wireless).
I'm assuming there are some settings I should be tweaking to possibly fix this but I'm not quite sure where to begin. Any suggestions? Thanks so much, and thanks for the great software
