How Much Time You Can Record on a DVD?

How Much Time You Can Record on a DVD?

A very common question I receive from owners of DVD recorders and persons considering a DVD recorder purchase is: "How much time can I record on a DVD?" This answer to this question for each DVD recorder is explained in both the published specifications (which are available online) and the user manual for that DVD recorder.

However, for those that are still in the purchasing consideration stage, here is an overview of the recording times available on a standard 4.7 GB blank DVD and how these recording times are labeled. These times are for single layer, single sided discs. For double-layer, or double sided discs, multiply each time by two:

XP - 1 Hour
SP - 2 Hours
LP - 4 Hours
EP - 6 Hours
SLP - 8 Hours
SEP - 10 Hours

In addition, some DVD recorders also feature HSP (1.5 hours), LSP (2.5 hours), and ESP (3 hours).

Also, keep in mind, just as with VCR recordings, the less recording time you use to fill the disc the better the quality and compatibility with playback on other DVD players.

XP, HSP, SP are the most compatible and provide what is considered standard DVD quality (depending on the quality of the source material)
LSP and LP would be the next best choice - which should still be compatible with playback on most DVD players at fair quality - you may experience some minor stalls or skips.

The remaining record modes should be avoided, if possible, as the video compression needed to place this much time on a disc will cause many more digital artifacts and will affect play compatibility on other DVD players - Also, the video quality would be very poor - about the same or worse than the VHS EP/SLP modes.

USB Battery

Batteries have reduced many a grown person to tears. Whether they're in your flashlight, Speak N Spell, laptop, or MP3 player, they always seem to be dead when you need them most. We can debate the pros and cons of other technological advances, but when it comes to batteries, everyone is in agreement that it's time for a better mousetrap.
A few new technologies, most available today, are worth looking at.

A USB/Battery Combo: The USBCELL battery can be recharged when you yank off its head to reveal a USB plug. Recharge the battery from your laptop or any other powered USB port. Snap the head back on and you're good to go. (About $19 for two batteries.)

No Pre-charging Required: Hybro, a new rechargeable battery from Uniross, is—unlike most rechargeable batteries—ready to use right out of the package without charging it first. The manufacturer claims it'll last four times as long as a standard rechargeable battery. It'll retain its charge for months and is rechargeable up to 500 times. Two AA batteries are $13.
