MAX Bitrate/Mbps for a encoded file for a WDTVLiveHub

Ive got a Hauppauge box that I can STREAM (via y/pb/pr from my Directv dvr into (co DRM on component)…

I record the video at 1920x1080 and 11Mbp/s, the PC is fast enough to record the video ffrom the haupauge pvr to the PC (99.9%) sure…

And occasionally im getting some blocky-ness while playing back the file on my wdtvlivehub.

The fileformat im using is MP4.

does anyone know the MAX Bitrate that the wdtvlive can handle playing back ?

thanks in advance

Is that 20 and 40 at the end of the line (below) the Mbps ?

cause 20mbps for SDTV and 40 for HDTV seem way super high (uncompressed digital unmodified files ?)

My Hauppage HD PVR2 1512 (which is the newest) will record at like 14MBPS for 1920x1080 60 fps… ?

So If I can give the WDTVLIVEHUB Box a 14 MBPS 60fps 1920x1080 it should be able to do it without choking up its processor ?

looking the above supported specs … 1920x1080 60fps is not in the list as ‘supported’ which may account for the occasional blocky-ness

I cant change teh 60fps, I wonder if that is or means a thing of interlaced or non interlaced or whatever, not sure. Thanks for the help :slight_smile: So it should be able to handle the recording I guess (MBps wise) just not sure on the 60fps thnks… thanks again :slight_smile:

It could be – you’d have to look at detailed media data to know.

The WD box can handle 60i (60 interlaced FIELDS per second) just fine; just not necessarily 60p (60 progressive FRAMES per second.)

I use a Panasonic camcorder for my home movies. It records at 1920x1080 @60fps in its top video mode. I can play these videos flawlessly on my WDTV Live Hub from the internal hard drive. MediaInfo :
