I have a Packard Bell Pulsar 300 PC (Yes, I know it's old). It has a 6-speed DVD drive, with 8 MB SGRAM and TV-out. My question is a very simple one. If I replace the DVD drive with a new CD rewriter, such as the MSI CR52-A2 recommended in PC Advisor as best buy, shall I still be able to watch DVD's on it? Sorry if this seems too simple but I don't know the answer and I don't want to take out the existing DVD drive and lose its facility.
