Hi Markus, Thanks for your mail. I have just joined the list today. 2006/11/17, Markus Rechberger <mrechberger@xxxxxxxxx>:
Hi, could you test: http://linuxtv.org/hg/~mrechberger/v4l-dvb-stable this should at least fix the tzap, this is just 1/4 of what has to be done to make it stable.
What problem with tzap? For me it works for Nova-T adapter 0,1,2,3. Not for device 4,5,6. I think it has something to do with udev device major numbers. I'm currently upgrading my laptop to Debian Etch which should give me a more modern udev. 1/4 of work to get v4l-dvb stable or just the drivers for Nova-T stick? Regards Peter
