video playback Hd 1920x1080 50p : troubles with ubuntu, but not in windows xp !


first, i'm sorry for my poor english...

i have a new camcorder SONY CX530
it does movies "fullhd" AVHD 1920x1080x50p, 24Mbits, codec H264, containair : MPEG-2 Transport Stream (.mts)

In Kdenlive, i make a project in HD 1080p 50fps profil.
But i have problem for rendering my movie:
- when i use H.264 profiles render, vlc, totem,xine,kaffeine, or other player have troubleshotting with the video. the reader software lost somes frames ... i don't known if you understand me?...
- i have sames problems with mpg4, xvid4, webm...

i don't have any problem with HDV PAL 1080 50i, but the format is 1440x1080... and it's entrelaced (i)

i have 1 computer who have 1 year, and a other 2 years... both in ubuntu 12.10, with the latest version of kdenlive stable 0.9.2

When i download movies on internet in 1080p or 720p codec h264 .mp4, i have no problem for read them.

so, 2 questions :
1) why i can't read my own film in mp4?
2) which parametrs can i use for do film in mts or m2ts format 1920x1080x50 Progressive ?.

Thank you a lot !



maybe your source insnt what you think it is?!

i try to open all my video test with windows xp on the same computer (dual-boot)
and i haven't any problem !
all my test h264,webm,xvid4...are ok with vlc or "media player classic" for windows....

ubuntu is worse than xp for read video ???
why ?

You've probably already installed Ubuntu Restricted Extras but if not, it might be worth a try.

i try with gnome player
and mplayer ,
and now it's ok ....
