Channel change Delay

[paulrbeers]

Question: I seem to have about a 3 second delay when changing channels in gbpvr. Is there anyway I can rid myself of this delay?

I your viewing on your PC monitor via VMR/Overlay, then enabling the SBE option can help channel change times. The most you're going to be able to trim off is about a second.

I thought one of the other big advantages of a hardware decoder was instant decoding? Or am I horribly mistaken? So if I'm inputting into my PVR-350, I would have thought it would have been a split second delay? I'm probably horribly mistaken.

Channel changing isn't instant because the data is converted to MPEG (by the hardware), then some number of megabytes of MPEG data is written to the hard drive (I'm using SBE and it's currently using a buffer of 95.5 MB), and finally the MPEG is played back from the hard drive and displayed on your monitor or TV.

Sorry for being misinformed but what is SBE I have seen the term before and can't seem to find out what it stands for.

sorry

Stream Buffer Engine. Its the technology Microsoft use for the Media Centre, and is available as part of XP SP1 or higher.

Nope - thats not one of the benefits. Hardware decoding is all about low CPU usage, and has nothing to do with how long the process takes.

Oh well, cheers for the info people!
