Isn't there still a question mark over whether the PS3 plays Pana AVCHD files?
This will play them:

If you are using the HDC-SD1 I would have thought that the nearest comparison would be the Sony HDR-CX6 which also records to removeable memory cards. The HDR-SR7/8 are HDD camcorders and I think you'll need to move the clips over to your PC with USB which can be slooooowww.
Biggest advantage of SR7/8 over SD1 (and CX6) is a viewfinder with dioptric adjuster, useful if you need reading glasses for close up work. Biggest advantage of CX6/SD1 is that they are a lot smaller, and you may find you can't be bothered to take a larger camcorder with you all the time. Result: no footage at all.
With an SD card, or a Memory Stick, you just take it out of the cam and slip it inot a card reader - most laptops nowadays have card readers - and Bob's your uncle. Move the files over to the TVix via USB or Ethernet (while you are asleep) and then they are all ready to play. OK, they won't be edited but the TVix plays then one after the other so they
look like an edited movie.
