[QUOTE="htpcoz, post: 124227, member: 13987"] I'm having similar problems with extremely long channel change times. I've found that this has come about since I moved from my old DNTV live card to a new DVICO Dual Digital 4 card. As with most people the DVICO software has extremely fast channel change ~2 seconds, however MP is generally very poor at 10-20 seconds. I can't see anything obvious in the logs that contribute to these delays, there seem to be a number of things all spread out by seconds each, no one item to identify as the culprit so far as I can see. MediaPortal Version: 0.2.2.0 SVN Build 12842 (although has been this way for some time) Skin: Blue 2 wide Windows Version: Windows XP SP2, .NET 2.0 CPU Type: Intel Core 2 2.4GHz HDD: Seagate 320GB 7200.10 Memory: 1G 677 MHZ Motherboard: Intel Motherboard Chipset: G965 Motherboard Bios: Video Card: Nvidia 7600GT Video Card Driver: 91.47 Sound Card: Integrated Azalia Sound Card AC3: Sound Card Driver: 1. TV Card: DVICO Dual Digital 4 1. TV Card Type: DVB-T 1. TV Card Driver: 3.50.02 2. TV Card: Hauppauge 150 MCE 2. TV Card Type: Analog 2. TV Card Driver: 2.0.43.24103 MPEG2 Video Codec: Nvidia Purevideo MPEG2 Audio Codec: NVidia Purevideo Satelite/CableTV Provider: HTPC Case: Antec Fusion Cooling: Power Supply: Remote: Microsoft MCE TV: Panasonic CRT TV - HTPC Connection: VGA->Component transcoder Attached is a log file from startup that shows some of the delays I'm seeing... From pressing "Live TV" after starting to the channel appearing is 20 seconds The first channel change takes 17 seconds, the third around 7, the fourth 14 seconds, and then 17, and 18. So pretty consistently very long. This is with timeshifting enabled. Disabling improves things by a couple of seconds, but still not much good. Changing the codec has not impact from what I can see. Can someone look at the attached log, and see if there is anything obviously wrong with this configuration? I struggle to believe that the card could be this bad (especially considering their on BDA based app is so quick). Note this is in Brisbane Australia, and I have a high quality antenna, with RG6 cable, line of sight to the broadcast towers, and no other issues. Thanks [/QUOTE]
