[QUOTE="Fingerswinger, post: 44651, member: 14559"] hi i live in switzerland, but the following problem occurs in all PAL countries in europe as far as i know. the problem is this: when watching a tv program with two different audio channels (with different languages) i am not able to switch between these channels by pressing "A". i'm not sure if it's exactly the same system as SAP in the U.S. in europe it works like this (PAL countries, with analog TV): most stations send normal stereo audio using two channels. when a station wants to send for example a movie with the original english soundtrack AND the translated german soundtrack they use one channel for english (which is then mono sound) and one for german (also mono of course). there is some type of hint in the TV signal that shows if the transmitted audio is mono (only one channel), stereo (two channels with stereo signal) or dual language (two channels with different languages, technically the same as stereo). now i know from an older hauppauge software-capturecard i have, that the capture driver automatically switches audio to language 1 when tuned to a station with dual language channels. i have a special tool (from hauppauge) to "force" the other language (this isn't necessary when using hauppauges own TV-application). i guess with the hardware-capture card (pvr 500 mce) it's the same issue. when switching channels i never hear the second language. to make things worse (or easier?): because of the nature of timeshifting or recordings it's not enough to be able to choose the audio channel when watching live-tv. you also need to be able to switch languages of recorded stuff. that means mediaportal should ALWAYS record both channels (force the driver to record both) and then let the user choose when playing back. really comfortable (but not really necessary for the beginning) would be if mediaportal knew about the nature of the recorded audio channels (from the PAL signal) and as soon as a dual-language-recording is played, switches to language 1 and displays a hint, that a second language is available (thats the way normal TV-sets do it). i put this under bugs, because obviously that functionality is there in mediaportal ("A" is for switching audio channels) but doesn't work (at least in europe). would be really awesome if this would work - so i could watch the simpsons the way they're meant to sound :D even without this working: mediaportal is awesome! thanks and keep it up! fingerswinger Area: Capture Card / Driver / Mediaportal Program (i can't tell) MP Version: 0.2.0 rc2 Skin: blue two Windows Version: Win XP Professional SP2 CPU Type: AMD 64 3000+ Memory: 512 MB (2 x 256 MB DDR-DIMM) PC-3200 Motherboard Chipset: ASUS A8V-E SE (Chipset: VIA K8T890 VIA VT8237R) Video Card: Gigabyte GeForce 6200 (64 MB onboard, max 256 MB shared) Video Card Driver: NVIDIA ForceWare 84.21 Video Card Resolution: 1024x768 Video Render Type: VMR9 Video Codec Type & Version: Mpeg2Dec Filter Audio Codec Type & Version: MPEG/AC3/DTS/LPCM Audio Decoder TV Card: Analog PCI card, Hauppauge PVR 500 MCE TV Card Type: Hardware MPEG encoder, analog, PAL TV Card Driver: official hauppauge drivers, WinTV-PVR-150 driver version 20_35_23348 Optional Log: i didn't find anything suspicious [/QUOTE]
