I have a Hauppauge WinTV Nova-t capture card. I have captured a few programs as the mpeg2 streams they are broadcast as here in the UK.

When I try to open these mpegs in VirtualDub, it says "MPEG Import Filter: pack sync error". When i try to them in TMPGEnc, it says "cannot open or unsupported".

Does anyone know whats wrong here? The streams play fine in IntervideoWinDVD, but I want to convert them to SVCD. Thanks in advance.
