| User review: | I had to create an xvid for ease of speed and compatibility for a senior citizen relative who is still using XP-they do! I did have problems though with her NTSC source dvd. I ripped a dvd(she'd previously purchased of course!) to herpc hard drive. I enabled the deinterlace option on Avi.NET and then at the start of the process received a warning message of: 
 'you are trying to deinterlace an already ivtc'd source.'
 
 I understand inverse telecine well and you should do this pulldown rather than deinterlace and maybe run a decomb too for combing issues like Handbrake lets you do. Avi.NET uses decomb plugin for deinterlace I see. Anyway I knocked off the option and the output was left with slight jagged lines as expected but 23.976 FPS nonetheless from 29.97fps. I also used the deinterlace option later out of curiosity and saw the same message, but got not combing and still 23.76fps. No visible differences between output and the deinterlace option did not ruin the image. I didn't use AutoGK to avoid the use of remove grain plugin on the source which was pristine. Anybody had similar issues like this with strange messages of ivtc? Thanks for any input.
 
 Anyway the software did a good job and everybody is happy.
