This isn't a difficult question, but it's bugging me because I can't say I confidently understand the answer. I see now that 1080p TVs are becoming more common.
If you take a PCI or USB DVB device and use it tune in a HD signal, how do that feed get displayed/converted to a PC/TV monitor? Let me clarify; currently HD signals are either 720p or 1080i. A computer monitor can display several different resolutions but are usually progressive scan (1280x720p or 1920x1080p). Once you've picked a resolution normally it will stay at that resolution and so it wouldn't change based on whether the channel you're on is 720p or 1080i.
Upconversion isn't new, but I've only ever seen it handled in hardware. That means it must be the DVB software that takes any signal and converts it to 1920x1080p (or whatever your HDTV monitor does). Do current programs support 1080p displays? Do some programs do a better job than others at conversion? Do some video cards do a better job than others?
