Receivers with firewire or USB digital output enabled do a better job. Unfortunately, that is only mandated in the US and only for OTA stations. There are a few firewire and USB add-ons that work well but they are expensive and very specific to one STB. (For example, I can't port my EV 169time firewire mod to Rogers, even though a similar mod is available for Rogers STBs.) The Hauppauge unit fills a popular, versatile niche, at least until component video is phased out or disabled.
