I would have to say I think there is a better approach that you should consider. Buy an external DVD recorder for your laptop. It will include the software you need to convert files and it will avoid the whole connect the pc to your tv step. Plextor makes very good drives and the software that comes with it is very good! Not only will it be easier to use, the end result will be much improved.
Reasons to buy a new drive:
1. Simplify connectivity issues with TV
2. You can burn faster than 1X (approx 8X-12X)
3. Video and audio quality will be much improved.
4. The software you need is included with most drives available. (assuming it is not white box or OEM)
Reasons not to buy a new drive:
1. Cost
The choice is simple if you ask me.
