Blu-ray vs HD digital?

Most currently offered HDTVs have a resolution of 1080p, and most also have a refresh rate that's divisible by both 60 (for the 60Hz refresh rate of video broadcasting) and 24 (for the frames-per-second rate that film is shot). That's why most LCD HDTVs have a refresh rate of 120 or 240 Hz. Plasma typically refreshes at 600 Hz.

If you have an older HDTV or one of the down-market models with a 720p engine, your TV won't even accept a 1080p signal, let alone a 24fps one. It'll accept a 1080i signal, but downconverts it to 720p.

Concerning the predominant resolution, however, assuming you have a 1080p HDTV, the only source I know of that will feed it its maximum resolution and refresh capabilities is a Blu-ray player. Over-the-air and cable HD broadcasts are 720p or 1080i. I don't know about satellite, but I suspect it's also 1080i or 720p. Apple TV HD downloads are 720p. HD Instant Watch programming from Netflix is also a max of 720p.

Only Blu-ray also offers 1080p output PLUS 24 fps (1080p/24) as well. This synchronization with the speed the film was shot at gives you better smoother motion with less judder.

I agree, go with the Blu-Ray player. If you buy a Samsung you can also stream Netflix, Blockbuster and Pandora.

I would add a Blu ray drive and ATI video card that allows bit streaming to a HTPC(Home Theater PC). This way you can play your BRs directly or you can use it for streaming network movies and shows.you can also use it as DVR for OTA or cable TV.

The HTPC allows you endless tweaks to video that standalone Blu ray players don't.

If you're a plug and play guy get the standalone. If you are a tweaker an HTPC. I rip all my movies to hard drive and share with the other PCs in the home. This way anyone on the home network can access the recorded TV shows or ripped movies. Every TV in my home has a computer plugged to it.
