NerdTv MP4s have no sound in GB-PVR? (my other AVI's are ok though)

[mixedup]

Hi,

GB-PVR is working great for most of my AVI files etc (fantastic, no more trancoding & burning to DVD)!!

The NerdTv (http://www.pbs.org/cringely/nerdtv/) video interviews however (*.mp4, e.g. ntvjuicy001.mp4) don't have any sound when I play them back in gbpvr. If I open them in QuickTime they do have sound. Try one of the "juicy bits" extracts from one of the interview for example (e.g. Andy Hertzfeld - The first Macintosh Programmer http://www.pbs.org/cringely/nerdtv/playe...mer...ever)

Any ideas? (is it back to mucking around with different decoders? or were the gbpvr config program decoder selection only for MPEG2 decoding). In this case I guess what I don't understand is how gbpvr targets the appropriate MPEG4 decoder, and how to adjust this? (e.g. if I could somehow select the same one that quicktime uses perhaps)

Thanks

PS. Have a look at NerdTv too!

Do you have sound if you play them in Windows Media Player? GB-PVR asks windows to select the appropriate decoders.

actually I do get the sound in Windows Media Player, but not in gbpvr - which setting should I tweak in gbpvr config? thanks

There is no setting you can change for this type of file in GB-PVR, it'll just ask Window's Directshow to play the file. Directshow is responsible for finding all the correct decoders.

On a clean machine I just download the klite codec pack (to get .mp4 support) from http://www.codecguide.com/download_kl.htm. I also downloaded one of the nerdtv episodes from http://www.pbs.org/cringely/nerdtv/. This combination seemed to work fine and result in playback with audio.

thanks - I was about to point out I had to manually open the file in Windows Media Player (i.e. wasn't a windows file assocation in place) - I'll try your sugestion out after work

So was there a particular gbpvr config setting to be tweaked, or is it just that windows has to be configured with an appropriate codec? (I think you were implying the latter)

Tks

Its the latter. I literally say to Window "play c:\path\to\file.mp4" and it takes care of the rest.

I didnt change any GB-PVR settings to get .mp4 support working.
