missing features or firmware bugs

[airsoft]

Hi all,

1) does anybody has tried Source button on remote control when device plays a movie (I've tested on MKV with 2 audio tracks and one external) ?
player uses only internal audio tracks, I've made the sample from BluRay Rip
Bad_Boys.mkv (h.264 + dts core 6ch + ac3 6ch)
Bad_Boys.dts
Bad_Boys.dtshd (the original DTS-HD MA)

2) mkv/avi movie with external subtitles .sub (MicroDVD format) from frame to frame

3) FLV container also does not work, but in YouTube menu it works, seems extension filter in Main menu Video is the problem... does not read *.flv

4) subtitles menu has no windows-1251 (cp1251) encoding, only way to play is to convert subtitle files from cp1251 to utf8
