Prof 7300 Problem on a 64 bit Computer

[jerry]

I acquired a Prof 7300 card and have had excellent results with 32 bit XP SP2 installed on a 32 bit machine with Prof version 1.1.0.4 drivers (using Dvb Dream).

When installed with x86 XP SP3 on a 64 bit machine results are not consistent. The Diseqc transmissions do not show up (with a recording scope) on the line to the lnb as they do for the 32 bit machine.

Similar failure occurs when using Prof beta x64 drivers with x64 XP SP1.

Likewise, failure occurs when using Prof version 1.1.0.5 x86 drivers on Win 7RC x86.

I updated the bios and all the motherboard drivers on the 64 bit Gigabyte mainboard to no avail.

I am curious as to whether anyone has had success using a Prof 7300 on a 64 bit machine.

Success was achieved on the use of the Prof 7300 PC card on a 64 bit machine with both the Win 7-RC x64 and XP x64 operating systems using PROGDVBx64. The PROGDVB program exists in an x64 version and of course requires x64 drivers and codecs which are available, many (codecs) within Win 7. When I inadvertently attempted to use 32 bit codecs with the XPx64 install it crashed in a hurry and for some reason its functionallity was also dependent on some unknown XP updates. I initiated the Win 7 install in parallel on a separate drive when I got discouraged with XPx64 progress. Both did work out.

The ProgDVB program is administratively awkward to use when the dish is slaved to a Motorola 922 for a dual lnb C-band dish or a C/Ku setup, but it can be managed. The DVB Dream program would be more convenient but its 32 bit format has a Diseqc control compatibility problem, where the solution is not obvious.
