I would have to say no. They product pdf file at their site makes no mention of progressive scan and I can't believe Bose would not mention it. After all progressive scan is still not on a vast majority of consumer DVD so for Bose not to not advertise it seems clear to me that it is not available. But having said that I can't say I'm 100% certain.
i helped install a new HDTV to a Bose system today and i only saw composite!! cables being run from the Bose unit, so i can safely say that there's no progressive capabilities there (at least in the system i was hooking up).
don't judge too harshly. My parents love AOL (cable and straight IE for me) but I have been able to show them the light and steer them from the evil BOSE corporation.
After reading this thread I decided to head over to Crutchfield Electronics. They usually feature very good pictures of all their products so you can see what kind of connections they have for yourself.
Anyway, I did a search for Bose and found that the Lifestyle systems do indeed support component video--if you pay for a special adaptor, which you must buy directly from Bose. Otherwise, the best you'll get is S-Video.
Ugh!
Anyway, here's a picture of the connections for a Lifestyle 28 system, in case it interests you. Looks like they're a bit short on video connections for a $2,500 system if you ask me.
Component video does not necessarily mean it is progressive scan.
If it is an adapter, I doubt it is true component video. It is probably some sort of signal splitter so you can use component cables. Defeats the whole purpose of having a component connection.
The whole thing sounds screwy to me. Probably just another Bose con job.
As a BOSE convert, just let me say, for the amount of money, you can always do much better than BOSE for any type of setup, unless you absolutely must have miniscule speakers and don't care about sound quality. I agree, if you have to buy a converter (which will be way over priced, as everything else they sell) then it is probably not even an actual component output, and almost definitely not Progressive. The build quality sucks, the sound is mediocre at best. Their speakers can't play high's and definitely can't dip very low, and misses a lot in between. Please do some more reading on here before you buy or recommend their products.
