Essence of a problem is that in tuners PV951series, that are tuners under titles MediaForte TV Vision PV951 and ProVideo (Acorp 3DeMon) PV951, IS SIMILAR THE REGISTERS GPIO WILL NOT BE USED IN GENERAL. By it, the installations of constants are indifferent in JTV .crd file. Very similar, that sound is controlled directly, through I2C-address. More probably, there is something intermediate for handle I2C, about which knows only native software. In programs of Bt878 diagnostics value GPIO_OUT_EN and GPIO_DATA when start in the native program and alternate - coincide. If together with the alternate program start native, the sound occurs and even is regulated. If to close native - a sound disappears. I have found possibility to include a sound in alternate programs, not loading native software of a tuner. I offer the utility PV951SC for turns on and off the sound.

It works simply: load the utility - switch on a sound - load JTV (bTV, Fly98) - look a television - close JTV (bTV, Fly98) - switch off sound - close the utility. That is all.
The utility simply includes a sound. As the crane with water. It will go even if any program of a television is not loaded. If a sound to not switch off back, that (on my computer - PIII-450, AbitBH6, 64M, TNT, SB Live!, the tuner is on-line to a linear input ) even Reset does not switch off. the sound, only PowerOff. I am not sure as it is all will work (and whether will be in general?) at connection of an external source signal (CVBS or S-Video).
I has directed on these thoughts by following: I have paid attention, that in JTV at choice of the channel 0, which is indicated as AV-Video for me , sound is not switched off, and goes from the last working TV link. Very much similar, that the sources of a signal switch in the same way. I shall try it to clarify in a near future.

About set-up JTV. To select right file .tun it is necessary to use I2C=0xC0. As file .crd is possible to take from any tuner on Bt878. Are important only PLLInit and three strings Video...
But on any case I have copied in .crd file values from GPIO registers:
PV951.crd
------------------------------------------------------
[Settings]
VideoTuner=0
VideoAV=1
VideoSVHS=2
GPIO_OUT_EN=0x00bff03f
GPIO_DATA_SOUND_TUNER=0x0E
GPIO_DATA_SOUND_OFF=0x0F
GPIO_DATA_SOUND_EXT=0x0D
GPIO_DATA_SOUND_MASK=0x0F
GPIO_DATA_SOUND_RADIO=0x0F
PLLInit=1
RemoteControl =
[Test]
Test=Test
-----------------------------------------------------
Remote unit too will not work with JTVRemote, since on the registers GPIO the pressing of buttons does not influence. It is DLL-file from native software, which services the sensor of a tuner - I apply . There only three functions - such as Init, Get_Key, Exit. But Get_Key Requires parameters. What - I shall try to clarify. If it may to be linked the same as I was linked for handle of a sound, it is possible to write the remote driver, probably. Yes, by the way, for me at home now lies Tekram M205 Pro, so I can test dialogue with it.

Actually, the problem remains: by standard resources of alternate software it decide not. Same concerns remote controls - it too is on-line nonconventionally. Is the thought, but is not present good knowledge of programming. Who can help, respond. This concerns to the developers of alternate software - these tuners exists, them buy and it is not necessary to wave away from them. It is necessary to introduce support to the programs.

Similar problem exists with a series of TV-cards Tekram M-2xx. I tried to make to work with JTV model M-205 under Win98. It is real, if first to load native software, and then JTV, the sound is present. If now to minimize native software on a task bar, nothing foils to use JTV (naturally, without remote). Moreover, sometimes, accidentally, I managed to unload native software so, that the sound remained live. The window JTV thus was freezed, but it was possible to closed and opened again - with a sound remained. Even after reboots PC through Reset. The situation in accuracy, as is described by Nikolay.
However attempt to use PV951SC was failed to me. The error is produced "PV951Utl Init DLL error!". There can be a business that in M - 205 stands Bt848, instead of 878, or is binding to the tuner.
Nevertheless, I was assured (!) by a friend, that there is a configuration of parameters at which M - 205 works with a sound - in program Fly98! These parameters were simply re-selected according to the guidelines of the writer, but at the present moment they are lost - are erased accidentally :- ((. While I did not manage them to select, can someone will be lucky more?

New, optimized variant (1.0.1) of the remote console for TV-card MediaForte TV Vision (PV-951) has arrived, authors - Andrew Moroz and Nickolay Zelenkov. Quote: "... If owners of PV-951 had to turn on sound by the separate program before, in the given version is realized automatic turning on/off sound at JTV start. It is necessary only that JTVRemote was loaded."

The subject continued as updated version (1.0.2) of the remote console drivers for PV-951 series TV-cards has arrived, author - Minaichenkov Kirill. Quote: "My tuner - Acorp 3Demon, while Nickolay have MediaForte PV-951. Basically they are two identical cards. In readme to the first version of the driver author did not guarantee its service capability with other cards. It was right! The driver was not work with my card. After code rebuilding I " have added support " of the Acorp card and a little interesting features also. In brackets I put this phrase that is possible also of any other card, and the word support is very loudly told, as 2 lines there are modified. I think, that this version of the driver will work on a tuner PV951 of any corporation. But, as is spoken, on 100 % I do not guarantee."
