Some other info/reading material:
Supported Recording modes:
The Panasonic DMR-E60 supports five recording modes. These are known as XP, SP, LP, EP, and FR.
XP: This is the highest quality recording mode that takes the most amount of storage space and gives the shortest recording time. On a 4.7 GB DVD-RAM/DVD-R it occupies approximately 1 hour of recording time.
SP: This is the standard recording mode that gives adequate quality and recording time. On a 4.7 GB DVD-RAM/DVD-R it occupies approximately 2 hours of recording time.
LP: This is known as the LONG recording mode that degrades picture quality but gives a lot more recording time. On a 4.7 GB DVD-RAM/DVD-R it occupies approximately 4 hours of recording time.
EP: This is known as EXTRA LONG recording mode it reduces picture quality to a higher extent then the LP mode and gives more recording room. On a 4.7 GB DVD-RAM/DVD-R it occupies approximately 6 hours of recording time.
FR: This is a unique recording mode; it captures the best quality picture in a designated time frame. On a 4.7 GB DVD-RAM/DVD-R it can capture from 60-360 minutes.

# Time Slip Function: The super-fast 22.16Mbps data transfer rate of the high performance DVD-RAM makes the innovative Time Slip function possible.
# Chasing Playback: You set the DVD video recorder to start recording at a given time, when the show begins. The problem is that you get home a few minutes later, while the program is still in progress. Before, you'd just have to wait or watch the end first and the beginning later. However, the handy Time Slip-function lets you play the show from the beginning, even as it continues recording to the end, so you don't have to wait.
# Simultaneous Record and Play: This is a convenient feature if you record a TV series. While you're recording this week's episode, you may want to watch the one you recorded last week. No problem. The DVD Video Recorder lets you enjoy simultaneous Record and Play. Provided both episodes are on the same disc, you can watch the one recorded previously while recording of the latest one continues.
# Time Slip Roller and Button: Just press the Time Slip Roller or Time Slip Button on the remote control once during recording to start playing back the scene recorded 30 seconds before. By rolling the Time Slip Roller, you can freely search for scenes in 1-minute units anywhere within the recorded section, while watching the playback on a small on-screen window.
# Direct Navigator: You can display a list of programs recorded on a disc for at-a-glance confirmation of the disc's contents. And if you move the cursor and click on a desired program, that program is displayed behind the list. You can also select programs from the program list and erase them, and you can use this function even during recording.
# Playlist Playback: You can select from among the scenes recorded on the disc and arrange them in any order you like to create your own original scenario, then save it as a playlist. You can also edit the playlists that you have created, and enjoy seamless transitions between edited scenes
.
# 160 GB Hard Drive: Allows you to record a favorite show off the TV, even while using the recorder to burn something else.
