Well...after doing all my tests I will try to explain the situation.
In advance, sorry for my poor english, I'm a spanish boy and I've never learned english in an academy. I just know what the internet has taught me
The tests were very quick because I have very little time for computer issues. I just used Nero and VCDEasy, both with MPEG images and VCD burning. I also tested to burn Mode 2 ISO CD with Nero in some tests.
Drivers installed: ASPI 4.71.2, Via Hyperion 4.48 (PCI IDE Driver), Miniport IDE driver (with IDETOOL utility).
NERO works fine and it's rock solid while burning. I can do almost anything and the buffer remains stable at 96%. When I think everything is alright the burning finishes and in the Lead Out part crashes with "SCSI command cancelled". The CD is readable but I don't get a good feeling about this error.
VCDEasy refuses to work. When it is ready to burn the image I get a "Write error in SCSI" and it stops. It says the error might be caused by a bad generic driver.
Drivers installed: ASPI 4.71.2, Via Hyperion 4.48 (PCI IDE Driver)
Nero works but I have the initial problem of my post. I can't do anything without trashing the buffer. The whole system seems to be slower than using the Miniport driver. A poor test I do is the HD test from Nero (in CD Copy mode). The primary HD gives me around 35000Kb/s while with the miniport driver I got 39000.
VCDEasy works fine but I get the same unstability of the buffer.
Drivers Installed: ASPI 4.71.2, No PCI IDE Driver from Via Hyperion (microsoft default drivers working).
I have more tests to do but by now I know that the problem is mainly in software because with all the drivers installed the system ran fast and the buffer was stable. In the other hand the burning software was not too much compatible or stable...
With all this new info can anyone know for sure what's happening to me? May all this strange trouble become from the 80 wires cable? I checked the Master/Slave assignments (jumpers) and all seems to be alright.
Thx very much for reading me and trying to help
