[mythtv-users] Cannot play recorded HD H264, advice on faster hardware needed

[klaas de waal]

Thanks for all the help!
The conclusion is for now:
- decoding this flavour of H264 in MythTV is not yet fully correct
- the decoding is a problem of ffmpeg and not of MythTV
- only one core is used in decoding
- when ffmpeg decoding for H264 is fixed then we need the fastest processor
there is for this content
- when ffmpeg is not only correct but also multithreaded so that it uses all
cores of a dual- or quadcore then a cheaper/low-power processor can be used.

Again, thanks for the testing and the clarifications,
Klaas.
