Tests show that many DVD drives will read CD-R's, but the resulting data is nothing that can be used. Second generation drives can read CD-R's, then, but the result is rather flaky. While most will read the disc and let you browse the disk in Windows Explorer, some refuse to play the movie on the disk. Unfortunately, due to the fact that this technology is new, these problems will probably be around a little longer while engineers perfect the system. Another compatibility issue lies with the MPEG decoder board.
Some boards cause problems in PC's when they try to work with the existing video card.
But, this depends on how you connect it. In order for this to work, your video card must have the right connector for the cable and must support the software specification necessary for it to talk. Other kits have you transfer video over the PCI bus to the video card or even have the MPEG card cables between the monitor and the video card. These two setups usually provide less headache. Finally, there is the OS compatibility issue.
