how powerful is PS3 showtime ?

Since I started using PS3 Showtime about year a half ago),I'm impressed by its awesome performance.Every now and then, the developer -thankfully- is releasing updates to make it more functional and bug-free .
It is known the app utilizes Game API to handle video playback but no information regarding what max bitrate and what specification it's capable of handling smoothly, Today I tried playing 22GB animation remux mkv movie (True HD DTS sound, 30 MB average bitrate) (full mediainfo ) ...to my suprise, the app played the movie flawlessly (played from internal HDD) .. but there was some problem when forwarding >30 sec as the app needs sometime to buffer the huge amount of bitrate ...overall , the app was up to the task and no complain from my side =) ...

Python script to check integrity of SFV files ...

SFV Checker in Python...
I was looking for alternative to sfv checker I used to rely on when I use Linux regularly ... some alternative tools were created on windows  but I thought of making my own script ...Python was my first choice..
usually I use Perl for my scripts,although the same idea(sfv verification) was doable in Perl but requires installing some Modules, so I decided to stick to Python.

here is a link to the script

How to use the script:
providing python is installed
Python sfv.py "sfv_file.sfv"
