Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
The problem with HDTV tuner cards is hardware encoding. I don't think anyone has come up with a HDTV tuner that supports hardware encoding on the card. This means you'd have to have a fairly beefy system to the encoding.
Also, the other problem is the current ATSC tuners only suport over the air signal tuning. Any encrypted singals (read: cable, satellite)sources have to be run through a set top box that supports a video out. I think this is done now, but its a hack.
