seas0npass XBMC - playback of AVCHD MTS files - should I buy aTVFlash?..

Hello guys,

I yesterday got my Apple TV2 and jailbroken it with AppleTV2,1_4.3_8F455_SP_Restore , installing XBMC later on.

One of the core reasons for having ATV2, - playback of my camera’s AVCHD files directly from NAS, is an epic fail :frowning: - buffering and interlace happens dramatically.

Question - is this a known issue? Any workarounds known? Any roadmap?..

And, most important one - should I buy aTV Flash, would I get a proper playback?

Here’s the file info:

Guys,

It seems like a software bug, as I managed to find almost identical file that ATV2 plays flawlessly?.. How come?..

It is even more “loaded” if you look at the records…

 

The only notable difference I found is :

 

The one that FAILS MISERABLY:

Scan type : Interlaced

Scan order : Top Field First

Bits/(Pixel*Frame) : 0.238

 

The one that works:

 

Scan type                        : Progressive

Bits/(Pixel*Frame)               : 0.098

 

 

Well anyway, this is probably something with either the AVCHD camera (Panasonic HDC-SC10) interlace, producing all those videos (It’s Panasonic , or XBMC - and probably purchasing FireCore wouldn’t improve this anyhow…

 

 

FYI Here’s the one that works in XBMC / Seas0npass and the info on the file that is played BRILLIANTLY:
