As for now... This forum is seperated by quality yes. DVDRips and HDRips are combined together. Since DVDRip is still the standard for now, this is how it will stay... at least until HDRips become the norm, then maybe we can do something.
If you type HDRip in the search it will come up with HDRips. But like I said, these rips are merged with DVDRips for now.
As for the Uploading... Uploaders are now beginning to switch to HD because of the demand. They are not much bigger than DVDRips. Between 1.2GB to 2.4GB. That's pretty good for HD and the quality is fantastic. I download HDRips as often as I can.
So thank you for the suggestion... we will consider this in the future as the HD market becomes ever more prominant in our community.
For the meantime... if you want HD movies, type in HDRip in the search, and choose DVDRip section or Movie Collections forums. Both offer and great deal of HD rips.
Keep those brains working on more suggestion and feedback.
