potentially stupid question regarding software HD playback

JasonWatkins · 18-08-2007, 16:14

ok, i've just invested in a new 19 inch monitor - the resolution appears to be able to cope with HD, and I have a graphics card that I know 100% supports HD playback.

So I tried a quick demo of an old movie trailer in HD at 720p, and the whole thing basically played on fast forward with garbled sound - although the picture was visible and did look pretty close to what I've seen of other HD clips.

So, am I going wrong somewhere along the way, regarding the garbled playback, or am I just mistaken that my monitor will cope with it ??

I understand that Power DVD ultra will cope with software HD playback, but then I'm on Linux ..

The monitor won't affect the speed anyway - it sounds like the software you're using doesn't work?. I don't use Linux, but there is plenty of suitable stuff about - even the Sony HD demo machines in the shops run Linux, and simply boot off the DVD drive (no HDD).

the closest i've been able to determine is "xine-hd" but i can't find it anywhere to download.

i just want to play the odd HD trailer here and there .. nothing special.

There are a number of codecs both proprietery and open-standard which are used to encode HD material, it sounds like whatever player you are using hasn't got the right codec or at least a version which is compatible with the file.

HD graphic cards even those with fully compliant HDMI and onboard acceleration will tend to focus on the main codecs such as VC1 and H.264 although generic mpeg4 may only get a boost.

Does it play ok in VLC ?

i eventually installed SMPlayer and it played fine on that, so I tend to use that as my player of choice now ..
