deinterlacing dvd playback problems

[2madman]

sorry if this is the wrong board but i recently purchased a brand new TFT monitor. (LG226WQT)

When ever i play a dvd in my dvd software(power dvd) and maximise to full screen I get scan lines. I believe this is a deinterlacing problem.

How do i correct this?

i have also used VLC player and try and tested the different methods of deinterlacing within the options of vlc.

Does this happen on all DVDs only certain ones? Try a film based DVD (basically any big release in movie theaters is fine) and see if you get the lines. If you do there are other issues besides deinterlacing, such as full screen tearing on your rendering surface.

If a known progressive, film based DVD does not show these problems, then it would help to have a sample of the DVD in question. http://www.doom9.org/mpg/dgindex.htm is a guide that can help you give us a sample. After you rip the VOB, open it in DGIndex, user the [ and ] buttons at the bottom to select a short (less than 30 seconds) clip where the problem is obvious, and go to file/save project and demux video. Upload the resulting .m2v to www.rapidshare.com and give us the link so we can take a look.

PowerDVD employs a number of different deinterlacing methods. The best method is hardware deinterlacing on your video card. Provided you have an Nvidia or ATI card capable of Vector Adaptive deinterlacing (ATI x1x00+ or Nvidia 7x00+), you should be able to see if it is using hardware deinterlacing by right clicking the movie while it is playing and going to options/information? (not home right now can't check). It should show that it is using DXVA for playback if hardware interlacing is working. If not, you may have to replace your video card with a newer model to get the best deinterlacing possible.

What did you need to do to fix it?

PowerDVD has very limited zoom functions, I'd recommend using Media Player Classic with FFDShow if you want more customization of playback. Here is a guide Jeremy Duncan of this forum wrote if you are interested http://www.avsforum.com/avs-vb/showthread.php?t=719041. If you don't want to go through all the trouble of setting up all those filters and plugins you can easily just install Media Player Classic and use it's internal MPEG2 Decoder to play back DVDs. It has a continuous zoom function that allows you to easily resize to anything your heart desires.
