Re: DViCO Fusion HDTV DVB-T Dual Express - When will it be

[stev391@xxxxxxxxx]

Allan,

I have had similar issues to what you have described, with usually good reception channels having degraded quality. 

One solution that I have used is to place an attenuator in line to reduce the signal. This card has a good sensitivity for low reception levels however the dynamic range of the card is not good enough to handle what the older more common TV cards require for reception levels.

I have had no issue with Chris Pascoe's drivers, the only problem is that his branch is now get dated and some of my other dvb gear does not work reliably under his branch.  This is why I'm trying to generate a patch that works against the v4l-dvb tree.

Also can you tell me what programs you are using to watch TV with?  With gxine I have no problem with my patch however when I run mythtv occassionally it crashes my tuner. I have yet to accurately determine why this is happening, and what I need to do to ensure that a userspace program doesn't crash my hardware.

Regards,
Stephen.

Hi Steve

I've been using Chris Pascoe's sources. I turned off the forced card
number and the auto-detection seems to be working.

I don't know if it's weather related or if it's to do with additional
interference from the card, but since I got it working, channel 9 (which
is usually very good) and ABC reception (which seems to come in and out)
has gone to unwatchable. Any thoughts on this? (should I run separate
cables from my antenna amplifier to each card, or is using the out port
on the Fusion Lite to the Express okay?)

I'm studying for an exam next week, but if you'd like me to test your
sources I can try that after next week.

cheers

Allan
