50p/60p is a dilemma that is getting a little better. It was not included in AVCHD 1.0 but was added to AVCHD 2.0 about a year ago. So, software and players are starting to work better with it.
- Copy the 50/60p files directly to a DVD as a data file. Newer Sony and Panasonic Blu-Ray players will play them as a data file. Note that this is NOT a Blu-Ray disk.
- Copy the files directly to a thumb drive or SD card as data. Those will play in newer Panasonic and Sony Blu-Ray players. The Panasonics have a SD card slot!
- Use software that came with your camera to make AVCHD disks. You can put up to about 30 minutes of HD on an ordinary DVD. My software makes "i" out of it, but the "p" files can stay safely archived somewhere. The AVCHD disks play in many older and all newer Blu-Ray players.
- If you have the bandwidth and patience, you can upload a 50/60p file to YouTube (I think!) and Vimeo (for sure.) But their software has to mash it up for distribution.
- Use inexpensive NLE software like the cheap versions of Sony Vegas and Adobe Premier to make optimized output for any viewing method from an iPod up.
- By a HDMI cord long enough to got from your laptop to your TV. Use something like Splash Lite as a player.
For me, I like to have a external HDD with copies of my favorite stuff as a backup. It is very easy to leave it plugged in to a WD TV Live media player (not the one with it's own HDD). The media player has a nice menu system and remote for convenient 50/60p playback.
