DVD Burning Tips
A DVD-Recordable or DVD-R is an optical disc with a larger storagecapacity than a CD-R,
typically4.7 GB (4.38 GiB) instead of 700 MiB, although the capacity of theoriginal standard was 3.95 GB. Pioneer has also developed a 8.54 GBdual layer version, which appeared on the market in 2005. A DVD-Rcan be written to only once, whereas a DVD-RW (DVD-rewritable) canbe rewritten multiple times.
The DVD-R format was developed by Pioneer in autumn of 1997. It issupported by most DVD players.

DVD Burning Tips
In a DVD-R, the addressing (the determination oflocation of the laser beam on the disc) is done with additionalpits and lands (called land pre-pits) in the areas between the grooves.The groove on a DVD-R disc has a constant wobble frequency usedfor motor control etc. Use high quality media. Defects in the media willcause defects in your written disc. Sometimes you can see physicaldefects in the media on the underside (where you are writing throughthe disc to the recording layerunder the printed side, or in themiddle of a DVD±R/RW). Physical defects include things likescratches, scuffs, stains, contamination, defects in the plastic,pinholes in the metal layer, or areas where the recording dye ismissing. Keep your hands off the disc... or at least theunderside of the disc. Dont use a "gorilla grip". Grabthe disc by stretching your hand across the topside, so you areonly touching the outer edges of the disc. Or, place one fingerin the center hole and your thumb on the outer edge.Fingerprintsor dirt on the bottom of the disc can cause distortion of thewritingor reading laser. Keep your discs dust-free. Store them in DVD casesor paper sleeves, or keep the spindle of blank discs covered. Before you burn, take a look at the underside surfaceof the disc. If you see any dust, blow it off with a gentle shotof clean, filtered compressed dry air (not by blowing on it withyour mouth). If you dont have clean compressed air, you cangently wipe off a dusty disc with a clean, dry cloth, but you runthe risk of scratching or smearing the surface. Never wipe discs in a circle. In general, it isnot recommend trying to clean discs. In an otherwise hopeless case,you can try some warm soapy water, without scrubbing the surface.Rinse with warm water and dry using a compressed air or a cleancloth. Plan your burn - figure out what kind of disc youwant to make. If you want to make the disc playable in an audioCD player, you cant format it as a ROM (data) disc. If youwant a DVD to play in DVD Video players, you cant format itas a DVD-ROM. Burn using Disc-at-Once mode whenever practical.Track-At-Once mode is meant to help avoid buffer underruns on slowercomputers, but causes overlapping sectors in between tracks called"link transitions". While this is allowed by the DVD specification,these discs are not suitable for use as a Master Disc for DVD Replicationfacilities, due to the digital errors between tracks, or possiblediscontinuity of the DVD timecode. In general, use Disc-at-Onceunless you have to use Track-at-Once. Turn off other programs, including screen savers.If you have problems with buffer underruns, you should choose aslower writing speed. You should also turn off virus protectionsoftware. For the best results, dont run any other programswhile you are burning. Keep your hard disks defragmented. While this isa good idea for better PC performance in general, it is an especiallygood idea for people who do a lot of audio or video editing, orother multimedia production. If your hard disk is highly fragmented,it will have to seek to many sections in order to read and writeeach file. This will slow down the transfer rate of data to andfrom the hard drive, and it could cause buffer underruns when burning.In general, dont let your hard drive fill up more than 75%to 80%. The hard drive fills up from outside to inside - the oppositeof CDs and DVDs. This is because the transfer rate is faster atthe outside, due to the greater circumference (a higher linear velocityfor a given rotation speed). So, the portion of the hard drive thatis written to when your drive is nearly full is slower than theportion that is written to when it is nearly empty. Also, a defragmenterwont run well or wont run at all when the drive is toofull, as it needs space to work. While higher speed recording saves time and generallyresults in great discs, slower speed recordings may give you yourbest chance for a higher quality disc, with lower error rates. Ifyou think you have problems, or if you have time to burn, slow yourburning speed down to 4X, 2X, or 1X. Use a felt-tip marker to write on the top of yourrecordable discs. Never use a ball-point pen, or roller ball pen.These pens could damage the recording layer, which is just beneaththe printed top layer. Dont leave open sessions. Unless you are storingdata in increments to a recordable disc (using multi-session recording),you should "finalize" your recording. This will allowyour burning software program to write a lead-out to the end ofyour session. This is necessary for compatibility with audio CDplayers. If all else fails, or to make multiple identicalcopies, save your project as an image file. For instance, if youare using GEAR's CD Burning / DVD Burning Software, go to the "Project"menu, and choose "Convert volume to physical". This physicalimage can be used to write discs. Keep in mind that some types of players, particularlyDVD video players, can not play back certain recordable disc formats. Try to keep your home movies to no more than anhour. Even the pros run into problems with longer DVD productions. Remember that your computer screen and your TV screenhave slightly different aspect ratios, so allow for that. Keep yourcontent, including your menus, near the middle of the screen. Avoid extremes -- in color, textures, and effects.And that goes for movie length and recording speed. Finally, don't panic. You'll learn by doing, andyou're bound to make a mistake or two. This isn't like copying toa floppy.
