[linux-dvb] Hauppauge Nova-T stick - no data output from /dev/dvb/adapter0/dvr0

Hi everyone,

I'm trying to get a Hauppauge Nova-T stick working using Ubuntu 7.04.

I have installed the latest cvs drivers (from 2007-10-10) and I'm
using the newest firmware mentioned on the mailing list
(dvb-usb-dib0700-1.10.fw), all to no avail.

Scan gives me no channels even though I know channels exists (see
below). Using a predefined channels.conf I'm able to use tzap to get a
lock on a channel (see below).

However, no matter what I do I am unable to get ANY output from
/dev/dvb/adapter0/dvr0.

cat /dev/dvb/adapter0/dvr0 > test.mpg (while tzap -r is "running")
will give me a zero sized file.

Any suggestions? Is this a bug?
