I'd agree with what everyone else said - the '80B does have speakers, they're OK for TV viewing but not great for movies, and down the line, adding some form of external speaker system would be worthwhile, whether it's a sound bar, a home cinema in a box or dedicated separates.
However, I think the second part of your query, about DVD recorders, has been overlooked so far. So here goes: my advice is to buy a Panasonic. That's not just because they're good recorders in their own right (and they are): it's also because Panasonic's Viera TVs now offer a system called Viera Link. This is part of the CEC standard (it stands for Consumer Electronics Control) which is written into later versions of the HDMI specification. Many manufacturers have adopted the standard (giving it their own particular brand name) and in theory, CEC should work across makes, but that's the theory.
Anyway: Viera Link greatly simplifies life. It means one remote can operate both components, and it allows your DVD recorder to 'talk' to your TV, and vice-versa. Sounds simple, but once you've lived with it, you won't want to go back.
Which Panasonic recorder to buy? Sadly, we've yet to take a look at the company's new range. However, I'd always choose a hard-disk-enabled model where possible, because it makes recording so much more convenient, so the DMR-EX78, with its 250GB hard-disk, should interest you. It looks like a straight replacement for (and improvement on) the five-star-rated DMR-EX77. To be on the safe side, I'd suggest you wait for our review, but if you really must get it sorted now, this is the model I'd look at.
