LG RH266 - Functionallity concerns



Hello i just purchased an LG RH266 dvd recorder with 160GB HDD and i would like to address a couple of questions.

A)I have not yet found if there is a way to transfer video capturred to the HDD to my computer.The manual says it’s possible to burn to a disc but i do not want to do that.(Mostly due to the transcoding there’s is to follow).
B)As far as mpeg4 goes does it only support divx playback,i tried xvid files but they were not recognized as an acceptable format,isnt there any way with a firmware update possibly to be a able to run xvid files?
C)And finally can i record any program from tv while i will be watching another channel.

I use the rf connector directly from the antenna to my recorder for the capturing.
