Hi folks!!

I'm doing my KDVDs with two 2 hour movies per DVD (usually 4 hours - DVD) using MAX bitrate 5000 MIN 300 , but the quality isn't perfect (using resolution 704x576, 352x576 sucks ).

I think that raising max bitrate to 9000 and min to 2500 would improve quality even lowering CQ... I'm I right? I'm not asking to compress a lot, 2 movies in a DVD seems enough to me... what do you think?

Are they widescreen or fullscreen? I think a bigger MAX bitrate will only improve fast-moving scenes, but slow moving may look worse....

Movies are 99% 16:9 actually, and my TV is 16:9 then ... widescreen

Do you think a higher max bitrate would affect quality? I cannot understand this... I think scenes with less movement with flat colors like walls or sky would improve their quality, Am I wrong? I hate seeing blurry colors on walls, jackets, sky and even faces, and this is the only effect that I can actually find on my KDVDs

Since you're a PAL guy, and you're doing 16:9 stuff, it's better to stay at 4:00 hour limit. High bitrate is used in high motion scenes, not slow motion ones.
Blurring may be caused by filtering (check your filters) or by shortness of bitrate. Compare the same scene at different bitrates (or CQs or q-factor) to see if this is the problem.
