free.fr (H264 channels) recording as mp4 issues.

[sgasp]

I have tried to record TV broadcasted free.fr channels and if it works nicely with MPEG2 broadcasted stream I have issue with recent H264 broadcast channels.

Using transcoding wizard I was able to register France 2 (Mpeg2)
rtsp://mafreebox.freebox.fr/freeboxtv/stream?id=201
without transcoding in a mp4 container and playing it back.

If I want to register the same channel broadcasted in H264
rtsp://mafreebox.freebox.fr/freeboxtv/stream?id=625
without transcoding in an mp4 container the output is, if playable, not usable.
There is a mask over it that just lets view 96 pixels width in the midle, the rest being black. Same mp4 file played with Quicktime player has no mask is 96 pixels large only.

If I choose a mpeg-ts container when recording I can play it back.

Doing transcoding does improve the mp4 output for VLC but not really for Quicktime, similar issue of size even if not the same.
Also transcoding is CPU consuming.

I have tried this on Windows and Mac OS X, so it looks to be a general issue.

Anyone encountering this ?
Any workaround ?
