Hickups while playing ISO and VIDEO_TS

Hi there,

I’ve installed my aTV 2G with the newest iOS (4.4.3) and aTV Flash Black (1.0). In MediaPlayer, I’ve connected my PC with SMB to the aTV. So far, I’ve got no problems but when I try to play a ISO of VIDEO_TS file (DVD5) the MediaPlayer isn’t playing the video smoothly. While playing, the audio is correct in DTS but the video has some hickups and isn’t playing smoothly.
How can I solve this problem?
