I got a 720p copy of a movie the other day and tryed it out in XBMC...streaming and from HDD....it was a .TS (transport stream)
The movie is rarely smooth.....and on the whole i got around 20 FPS, instead of 30..which it should be.
When the PC sends a 720p .TS (transport stream) Digital TV signal in standard definition(SD) to the xbox...will the xbox be able to play it smoothly?
whoops! sorry, my mistake.. I said SD was 720x576p (progressive), when actually it is 720x576i (interlaced). The 576i SD .TS was playing fine on my XBOX when using a networked SAMBA share and XBMC (Feb version I think). I'll need to check the 576p (Network 7 and SBS HD) and see if they play ok. Channel 9 (1920x1088i), Channel 10 (1440x1088i) and ABC (1440x1088i) forget it.
I've also tried NTSC HD playback thru the XBOX and it stuttered too much (Van Helsing and The Alamo HD trailers). A Dreambox mod would prolly have the grunt though - anyone out there with a Dreambox (1.4GHz XBOX) comment on HDTV playback using XBMC?
