I'd recommend more RAM. You can solve a TON of problems. It looks like you have 256mb RAM. 167 of which is free. Your computer must be swapping/paging like crazy.

I've found that more RAM on the PC speeds up the burn, and allows for larger burns with fewer errors. You can speed up your whole system at the same time. As you may have experienced, the minimum requirements just barely work. Typically you need 2x that level in order to get good performance.

Also, when burning, (disconnect from the internet totally) and turn off your A/V. it may be intefering with the burn.

Every Piece of Electronic Equipment runs on a finite amount of smoke. The systems are normally very efficient at reclaiming the smoke and recycling it, however, should you do something to let the smoke out, your system will become useless.

SAVE THE SMOKE !!
