Any live CD/DVD or none at all
Any linux distro with the codecs, plugins etc pre-installed will be dependent upon bug testing on different architectures and different systems (32 bit, 64 bit, laptop, dual core, etc.). The more testers out there the better the likelihood that your particular system is bug free. Unless you're willing to install packages to a base system, you'll just have to try different distros until one works out best for your particular system. I've had my best success with Mepis, but primarily have used HP laptops and desktops over the years. You may want to post your particular system, and then ask the forum who has had out-of-the-box success for the same system.
