For people recieving on the VHF band with the Hauppauge dual tuner (Mainly Melbourne Metro people), you will more than likely have issues with SBS and ABC stuttering.
I have contacted the Australian Distributors (newmagic) and they assure me that it is a driver issue and that they are working with Hauppauge to develope a fix. Apparently SBS and ABC transmit something that is causing problems with the error correction. They told me they hope to have a solution in about 2 weeks and that they will post info/updates on thier website when it becomes available

An exchange was not possible as its not a hardware problem
Hope this helps someone out
