I also moaned on here 2 months ago about my 4meg uncapped Mweb account t.
I was having issues with Netflix, hulu, iTunes Apple TV and YouTube streaming in particular. It would buffer for 5 minutes, I kid you not, and play for 1 minute and then buffer again.
My complaints were falling on deaf ears as Mweb thinks all is well on their network. Then the seacom thing happened and I decided to get a telkom Internet 4meg uncapped account. I also still have the Mweb one, just to compare.
Guys let me tell you, not only is the telkom one almost half the price of Mweb, but my torrents are running at 450kbps even during the day. Streaming is a breeze, even HD hulu. My brother was having the same issues with Mweb so I got him to switch to TI too and all his problems are fixed. He's on a 2meg telkom uncapped and it's streaming better than an Mweb 4meg account.
