Continue your search for a way to spend money on another piece of hardware to add clutter, heat and power consumption but in the meantime download NextPVR[FREE] and install it(10 mins). On your PC watch a vid, stop it,open another, stop it it and go back to the first one and pick up where you left off. If you're satisfied look at the back of the PC and consider your options to port video and sound to your TV. I don't think the HDMI cable will port sound to the TV. I use a 7pin S-video and a 5.1 speaker setup (my tv is only 720p).
If you do like NPVR it can support lovely metadata to make browsing for a video or music more blingy
@jshel101 NPVR can be used without a tuner and it's pvr functions to access media anywhere on the LAN and remembers the point that you stopped the vid before it finished which meets the criteria of the OP.
