If you're having problems with Anydvd or other Slysoft software, you might want to remove these other programs: 1. Musicmatch Jukebox visit http://forum.slysoft.com/showthread.php?t=1293 2. Pinnacle software VOB Instant Drive (virtual drive, which uses ASAPIW2k.sys) Pinnacle InstantWrite (packet writing software, which uses cdrdrv.sys) Other Pinnacle software may install ASAPIW2k as well visit http://dvdxcopy.afterdawn.com/thread_view.cfm/44/48261 also visit http://forum.slysoft.com/showthread.php?t=203&page=4 3. Packet writing software in general (directcd, incd, etc.). If you want this functionality, I recommend using DVD-RAM burners instead. 4. ONES, Zulu2, Recordnow! 4 and Digion Audio (PzWDM) visit http://forum.slysoft.com/showthread.php?t=998&page=2 5. Nero's Incd 6. Directcd (possibly) 7. Arcsoft Photo impressions (or anything that installs afc.sys) 8. Dragtodisc 9. Drive Letter Access (more packet writing software from Veratis/Sonic Solutions) 10. CyberLink InstantBurn (more packet writing software) 11. Iviaspi.sys (sometimes installed by Windvd) source: http://forum.slysoft.com/showpost.php?p=36523&postcount=9 12. Spybot Teatimer (only conflicts when installing) 13. DVD43 (can cause conflicts with Anydvd; moreover dvd43 only decrypts CSS) 14. Installing Winamp with burner (sonic/roxio) plugins can cause problems, apparently: click http://forum.slysoft.com/showpost.php?p=180400&postcount=42 I'm keeping this thread open in case people want to add to the list or discuss the conflicts. This is not a a definitive list, and it's entirely possible some software listed will work on certain systems with Anydvd.
