Hi there, Just got myself a Denon-1911. The system will auto detect whether it is DTS or Dolby audio. However, how do i choose between so many download in the net? AAC3? H264? Or i just find those mkv files, then it is DTS for sure.

Does big file indicate anything? Clarity in video? or Audio?

Thanks in advance.

U got all the information wrong. AAC3, H264 does not gerenti DTS. And from my own experiences... those rip rip rip normally doesn't come with DTS. They only provide 6 channel effect. You could always verify it from the source before download. Just my 2 cent. Don burn me if i am wrong.

AAC,AC3(Dolby Digital),DTS = Audio Codec

H.264(X264),Xvid,Divx,Mpeg2, = Video Codec

AVI,MKV,MP4 = Container

If i'm not mistaken, AAC and AC3 are not the same.. i mean, if the AV says it can decode AC3, it doesn't necessarily mean it can decode AAC (like my AV amp).

So far, movies that with named DTS work with my amp. The amp will detect that DTS is available.

file size indicates how compressed the movie is..

a HD movie can be compressed to a small as 1GB from a 40-50GB Bluray disc.

a 720p rip will have smaller file size than a 1080p rip

most HD movie compressed to mkv these days. some m2ts, ts etc...again, the type will affect file size.

the audio codec also determines the file size. AAC, AC-3 is normal DTS audio...

movie with HD audio like HD-MA or TrueHD will make file size larger.

general rule of thumb, the bigger the file size, the better the quality (both audio & video)...avoid anything smaller than 4GB...above 10GB is good, above 20GB is better...uncompressed is of course, the best.
