You need to provide more details such as RAM and total Hard Drive space. Since HD (High Def) video takes a huge amount of storage space, you need to make sure you have enough. Because of the processor, I see you have a laptop. How much space is on that laptop? AVCHD (the format in which High Def video is recorded with HDD/DVD/Flash camcorders) requires a lot of processing power and RAM, so your experience with AVCHD might not be "fast".
Another thing, you won't be able to get the High Def video onto your TV unless 1) you buy a BluRay (High Def DVD) player or 2) you connect the camcorder directly to the TV. This is because the HD video will not fit on a standard DVD or work on a standard DVD player.
Also, you will need video editing software in order to edit the AVCHD video that specifically supports the AVCHD format. There are plenty of choices now from ~$50 to $500+. Remember, the included software is BASIC, at best, but it will allow you to view the HD video on your computer and make a standard definition DVD for your DVD player.
If this seems like too much of a hassle, there are other options such as HDV (tape-based). Just remember that HD tape camcorders can take as much as 30GB of hard drive space for each HOUR of recording. A kind suggestion: For any camcorder you decide, buy an external hard drive along with it.
