I have the same problem with AnyDVD v18.104.22.168
When I insert a video DVD into my DVD-RW drive, the DVD is detected and autoruns, WinDVD v4 loads and tries to start the playback, then stops with a WinXP request to send an error report. The technical info contained within the report is quite lengthy.
I have tried un-installing and re-installing WinDVD v4, but it didn't help.
Next I removed the WinDVD v4 software and tried PowerDVD v5. Same results...no video DVD playback.
I have also tried Windows Media Player v9 just in case...no video DVD playback.
Next, I un-installed CloneDVD and AnyDVD. Video DVD playback works again.
Then, I re-installed CloneDVD v22.214.171.124. Video DVD playback still works.
When I re-installed AnyDVD v126.96.36.199, video DVD playback failed again.
Through all of this, my DVD-RW and CD-RW drives work just fine with CloneCD v188.8.131.52 or Easy Media Creator v7 to burn CDs, or to read and play game or music CDs.
I am running WinXP Pro SP1 with all patches except SP2, on a nVidia nForce2 chipset motherboard, using the latest nVidia chipset drivers (v5.10).
My DVD-RW drive is a Lite-on SOHW-1633S with firmware ver. BS0S. IDE chan 1, Master (Secondary Master). Secondary Slave is a Lite-on LTR-52246S CD-RW.
I have tried swapping Master/Slave jumpers, with the same results.
I would really like to be able to use AnyDVD...
