I bought my MBP 13" (2.4ghz) just 3 months ago - I am considering buying an HDMI adapter but heard about problems with HDMI output on the macbooks? If that's the case should I wait until Apple fixes it (if it does at all)?
i have not heard of any issues with the hdmi cable out of a mac, there is no special software for it, just a higher resolution and faster cable then your regular AVI, i am running the regular avi out of a macbook 13" and it works great no lag or res issues (13" macbook - 26" lg tv)

"On some noncompliant Mini-DisplayPort to HDMI adapters, the audio signal may not be passed to the HDMI device."
EDIT: so apparently only certain MiniDisplay ports (after April 2010?) transmit audio as well as video - did a few quick searches on Amazon to find the ports that do support audio

The 2009 won't support audio, but you can buy adapters that plug into the MDP and USB which go to an HDMI. I think a simple google or amazon search can find you those.
