The first WinTV-PVR to gain popularity was the PVR-250. The original version of the PVR-250 was a variant of the Sag Harbor (PVR-350) which used the ivac15 chipset. Although the chipset was able to do hardware decoding the video out components were not included on the card. In later versions of the PVR-250 the ivac15 was replaced with the ivac16 to reduce cost and to relieve heat issues. The PVR-250 and PVR-350 were joined by the USB 2.0 PVR-USB2 to complete their generation of devices.
