MagicDVD drives cannot accept DIVX discs. DIVX discs are purchased, and with it, 
you get a 48-hour viewing period that kicks in when you insert a Divx disc and press 
"play." If you want to watch the movie after that, you have to call the service and pay a 
fee via credit card, and the service renews the license to play the disk for a limited 
time, or, for yet another fee, permanently. 
 
What does “overlay surface not supported by your display card” means? 
 
PowerDVD requires your display card to support DirectDraw overlay surface, so that 
DVD subtitles can be properly displayed. Please refer to the Choosing DVD Playback 
section for how to determine whether your display card supports DirectDraw overlay 
surface. If you do not want this message to be shown again, either simply check the 
option Do not display this message next time or uncheck the option Show warning 
messages. If you would like to re-enable this warning message, simply check the 
option Show warning messages again. 
 
What Are the Differences between Hardware and Software DVD Solutions? 
 
The main difference between hardware and software DVD decoders is CPU utilization. 
Software DVD will utilize a much larger portion of the CPU. A software decoder has 
the great advantage of not taking up a PCI slot in the PC and has equivalent 
performance to hardware. 
 
Can I Run Other Programs While Viewing A DVD Movie? 
 
It is not advisable to do any multitasking while viewing DVD content. Running other 
software while watching DVD content may produce video corruption. 
 
Can scratches affect a DVD disk? 
 
Most scratches will cause minor channel data errors that are easily corrected. Major 
scratches may cause uncorrectable errors that will cause an I/O error on a computer 
or show up as a momentary glitch in DVD-Video picture. DVD data density is 
physically four times that of CD-ROM, so it's true that a scratch will affect more data. 
But DVD error correction is superior to CD-ROM error correction. It's also important to 
realize that MPEG-2 and Dolby Digital compression are partly based on removal or 
reduction of imperceptible information, so decompression doesn't expand the data as 
much as might be assumed.
