Thread: Experience with the Prof 7300 PC card

I acquired a Prof 7300 card and have had excellent results with 32 bit XP SP2 installed on 32 bit machine. Using a Tektronix digital scope with a breakout box on the lnb input the Diseqc transmissions are as expected. Dvb Dream has been the application used and the PROF drivers were the original 1.1.0.4 version.

When installed with 32 bit XP SP3 on a 64 bit machine results are not consistent. The Diseqc transmissions are seldom present. The bda.log file shows they were sent but the scope does not trigger (single sweep recording with either plus or minus 250mv level ). Tests with the 22Khz were also made. Once in a while something shows up.

I have updated the bios and all the motherboard drivers on the 64 bit Gigabyte mainboard to no avail and am using the latest online drivers version 1.1.0.5 after originally trying the 1.1.0.4 version.

While PROF limits the operating system to being 32 bit there is no mention of such a limit on the hardware requirements.

A friend is getting the PROF 7500 USB version which I hope to evaluate on both machines.

Where did you get this idea? Why don't you try a 64-bit driver for Prof 7300 from
here

? Similar 64-bit driver for Prof 7300 is
available


, and for Prof 7500 USB is expected later.

See the page of the PROF web site at the following link:

Prof Red Series DVB-S2 7300 PCI




The first line under System Requirements reads as follows:
OS: Microsoft Windows 32bit 2000/XP/Vista/Win7


The drivers you referenced are for a 64 bit Operating System as can be noted in their respective INF files. My prior post referenced a 32 bit operating system on 64 bit hardware.

The page you mentioned wasn't corrected yet. The 64-bit drivers are in beta. Nice dishes though on your avatar.

I very much appreciate you referencing of the 64 bit beta drivers for the PROF 7300 as that opens up a whole new ballgame for me on the 64 bit machine.

It was looking like I would have to continue network streaming from the 32 bit machine to the 64 which in turn forwards it over HDMI (60 feet) to the principal TV.

Whoops, I may now have to eat my last words on the "whole new ballgame" at least for a while. I just received a reply from dong.prof.tuners as follows:

Jerry,

But we don't know good DVB-S/S2 TV-player for x64. You will have problem with 32bit software (DVBViewer, DVBDream, etc) on x64 system. Sometimes you will have BSOD, because all satellite software 32 bit.

x64 not for satellite TV

Of course, its just a matter of time for all DVB packages to start moving towards 64 bit support. Don't take this reply to your bank.

I installed a fresh copy of XP x64 (evaluation) along with the beta x64 drivers (referenced by both zamar23 and PROF) on the 64 bit computer (using Dvb Dream, an x86 app) and the results were consistent with installing Win x86 and the x86 drivers on that 64 bit computer -- similarly limited success even when bypassing the Diseqc. Interface problems between bios and drivers for the x86 case or between the x86 application and the x64 drivers in the other do not seem to be the only problems as I initially surmised.

Previous usage in Win 7 RC x86 with the x86 drivers, also had no more success. I hesitate to even experiment in the Win 7 RC x64 drive at this point.

Interesting report. Did you post your findings on DVBDream's site, asking to update to x64 version? I think, lack of a complete solution for x64 bit support will start hitting all card makes pretty soon, as North American users actively move to newer hardware. But the front runners with x64 drivers available will always feel the heat first.

Do you know any card make that supports x64 hardware with its own complient driver and viewer application? Such suggestion may help.
