Just have a few questions

1. what is bdrip or brrip?

2. Is it better than blue ray or 720?

3. Also most bdrip/brrip are in mkv/mp4 format but this movie is in avi but it says quality detected
bdrip what does that mean?

4. Last but not least some movies in mp4 format say 720 brrip/bdrip in the titile but quality detected says dvd or hd why is that?

BDRIP means an encode directly from a source Blu-Ray disk..
BRRIP means an encode from a Blu-Ray release...say 1080p mkv(normally)..
both are blu-ray(not blue ray)..720p denotes the dimension of the movie..
blu-ray is always high-quality but its quality gets reduced with size..

yes..almost all blu-ray encodes are in mkv or mp4..this is because of the format specification..h.264 encode results can be achieved through mkv and mp4..
if xvid is used instead of "h.264" , then it can be in avi(most of them prefer this) as avi format supports it very well..and also most layers can play avi and not mkv..this is also a reason..

no..this wont happen..if the movie is encoded from a dvd source, it says dvd-rip..if it is from a blu-ray file, it says brrip, if it is directly from a blu-ray disc, then it says bdrip..thats it..

some people either lie or don;t know so they say DVD rip are 720p when they really are not...go by what the detection says before what the uploader says. Also look at comments b/c people will talk about that!!

@shade_21
dont spam your question in torrents(via comments)....you have posted here..just leave it..

Dude thanks for clearing all that up appreciated. I have seen torrents labelled as 720 brrip/bdrip with detected quality as dvd ill post the links give me a moment.

sorry didnt mean to spam juss needed clarifying...u know how it is these day instant gratifaction generation sorry bout that....

a lot of people get confused with the 720
DVD 720x576p and they think it's a 720 when in fact it goes from the last mumbers..
compared to say a blu-ray of 1280x720p
many uploaders write 720p which does confuse people quite a bit and if they provide the info in desription sooner or later peeps will pick up the difference of the two..

So is there a program/software that can tell you what quality of media you have?

http://mediainfo.sourceforge.net/en

media-info can tell different aspects..video format, size, length, codec format, bit rate, dimensions, audio format, frequency, audio bit rate etc...
