I don't mind the bad quality videos because some are old, or shot with old video cameras, some shot with a mobile phone etc - so why is that not ok with some people.?..the clue in in the length of the video...and if its tagged with ametuer...some people complain and protest too much!!
So, here are some categories I would like to see added, and could you up the number of niches when uploading - three seems a bit restrictive in some cases?

Black-woman (you have redheads blondes asian indian etc? and ebony tends to be interracial)
Fetish (no category like this on upload)
Big Cocks (???)
Roleplay (seems a good sub category for some videos)
XY-sex (sex between short & tall, fat & skinny, old & young, aliens & humans etc?)
Greyheads (Like redheads? some people like grey hair and mature/granny implies it but isn't)
Clothed
Skinheads (Q-Balls)
Freaks (Lol!)
Non-PC (politically incorrect/racist /ageist/classist themes etc.)

how about a category for costume, cosplay

Anilingus
Cunnilingus
Piss

Peeing vids and pics, now this does not need to be hard core material(possibly the tamer side of things), seems to be a lot of followers on her to this type of material...

I think you have enough categories but what we would like to see is to post ones material into one (1) category. We're seeing the same material in multiple categories.

you porn has an asslicking category why does x hamster not. ass licking male to female. no male assholes pls.

do it pls

How about adding a Female 2 Male Strap-On Category,A Category that has videos of Women Fucking Men with Big Strap-Ons.

Is it posible that there is no deepthroat category ?

add a amature master/slave cat pls

Maybe list of pornstars like for example preview of Julia Bond and when i click it show me al of her vids.

Master and Miztresses cat pls

HIGH DEF!

I believe all the material in the 'Anal' niche ought to be separated-out into Anal-homo and Anal-hetero.

if a video persistantly gets a low rating from users it should be deleted

I want the categorie "Painal"

Cuckold, hotwife, swingers,

i would like a housewives category please :)

And also a better tagging system. Often, videos are misplaced in the wrong channels...people don't know the channel they should put their vids :S It's very frustrating!

Get some mods or admins to properly tag videos and put them in the right category/channel please!

d abord je suis tres satisfait par cet enorme choix de videos mais je voudrais savoir si on peux utiliser un autre lecteur de video comme VLC MEDIA PLAYER OU DIVX PLAYER?

second the rimming catagory. you porn has one. there is enough interest and it makes me hard.

make an ass licking section now god damn it. C:

just thought id add thats chicks asses i like to see getting licked not the other way around nothing worse than seing a dude get his salad tossed.

a lot of us now have high def that would be great
even dough u r already great
u could b and will b greater
i love xhamster a lot so
keep it up like i do
