As you noticed while some groups release material lukewarm TV standard (SD). Notusing XviD codec but one X264.
Compared with XviD, x264 is able to provide high quality and compression at higher resolutions.
Not to be confused with material 720p or higher!
No need for improved system to track these materials.
This category is dedicated only serials, TV shows and so on.
I created a new category, SDTV.
This will generally contain materials x264 codec with resolution less than 720p, which isgreater than or equal load will continue to HDTV.
