Ok i am a newbie and just started doin this 2 weeks ago, i have encountered a couple of stuff which i am confused about, please help me.

i live in Aus so all my dvds i rent are PAL Region 4, i have heard you should only use Forced Film on NTSC DVD's and never use forced film on PAL dvd's, is this true and please explain ??

when i watch a DVD and sound is on 100 % it still isn't enough, is there anyway (perhaps with LAME) i can make the audio louder and keeping it in sync with the video at the same time ??

ok now the issue of Interlacing, when i run dvd2avi and open up my Vob files, i press F5, this tells me stuff about the movie, i.e. the region which is PAL and whether it is interlaced or not. Every time the DVD is interlaced which means i have to run a deinterlace filter. Is a deinterlace filter the best way to remove interlacing and whats the best way ? Should it be removed ? and does quality fall when deinterlace is run, whats better, leaving it or deinterlacing it??

ok now last one, the issue of 1 pass and 2 pass, i use the Divx 4.12 codec for compression using Virtual Dub. Now i did the matrix with
1 pass, forced film and interlacing, the video looks excellent but is jerky and the interlacing is bad, i then did Final Fantasy with 2 pass, no forced film and deinterlace filter, the interlacing is merged together so its not too bad but you can sometimes see the 2 lines merged and its not a clear crystal picture, clear up this issue for me please?!

thanks!!

Hiya...

Yep, you shouldn't use Force Film on PAL DVDs. If you find your DVD has interlace effects, I suggest using Smart Deinterlacing. I usually use Gordian Knot's default setting, it seems to give good results (at least for those movies that I tried). Other people on this board might suggest some better settings for the deinterlacing. I think with Smart Deinterlacing you get less (or no) ghosting effects and clearer picture compared with normal/fast deinterlacing.

As for your audio, why don't you just turn your volume higher? :p
Seriously though, I'm not too sure. Maybe someone knows?

You said your DVDs are PAL, so of course The Matrix turned out jerky cos you used Force Film. As for picture quality not clear when you deinterlace...read first paragraph.

Hope that helps! :)
