I use PSP Max Manager Pro to download videos onto my PSP and all of the videos turn out to be very low quality whenever I play them back on my PSP. I convert the videos to maximum quality, but it doesn't change. Why is this an issue?
I much prefer the converters that tell me what they are doing, as opposed to settings like "low-high". I usually convert using AVC at approx 400kbps video. I find that to be a good compromise between size and quality. As the other poster stated, this only makes a difference if you're converting a good quality movie. If it's low-res originally, converting isn't going to magically improve anything.
