- TV (Can I get a satellite dish that supports NTSC and gets US programs?)
Nope. The satellites carrying US programming are on the wrong side of the planet.
- Computer (Can I swap out the power supply? Are there other issues besides power?)
As mentioned above, just get a new power cord and flip the 110/220 switch, if there is one, next to the power cord socket. Some PC power supplies are auto-sensing and will happily run on whatever they’re plugged into with no changes needed.
Stuff like your network router may or may not have an auto-sensing power supply, so you may need to buy a European power supply (assuming it has an external supply). Ethernet is a global standard, so if you need to buy a new router, there shouldn’t be much trouble. Strangely, it may be cheaper, or at least not cost-effective, to buy a new router entirely, rather than hunt for a European power supply.
If your router has a DSL or cable ‘modem’ built in, you may as well dump it before moving. I’m pretty sure American DSL and cable broadband are different than waht’s used in other countries.
Printers and monitors may or may not be auto-sensing for power. Both of my newish LCD monitors show “100-240 volts, 50-60 Hz” near the socket for the power cord, as an example of what to look for.
You will need a new DVD drive, or do some googling to see if it is possible to change the drive’s region code. Right now, your drive is going to be set for Region 1, so European DVDs won’t be playable.
- Stereo
Newer ones can probably be re-programmed for the European station frequencies and station spacings. You’ll need a power transformer with enough capacity to run the amplifier. (A small kitchen radio probably only needs 50 watts, but a big home theater rig will need a lot more.)
- DVD player
These have gotten cheap enough to be not even worth moving across town, much less across the planet. Give it to a friend or have a yard sale. As with the DVD drive mentioned above, you’ll also have region code problems if you buy or rent DVDs in Europe. Happily, a lot of European DVD players don’t care what region a disc is from, so you should be able to play your existing collection.
**- Kitchen appliances (Blender/electric mixer/etc) **
The hassles of needing power and plug adapters, plus the bulk and weight of the appliances makes it more sensible to buy new appliances after you move.
