Hello,
I've tested my AverMedia Twinstar (A825) against the latest antti's
git repository, branch it9135_tuner. The following patches make the
stick works in dual mode with all the currenty available firmware,that
is:

The two adapters works quite reliably, adapters can perform scanning
independently and at the same time, and all channels get recocgnized
by both of them.
However, there are some sporadic image glitches while watching a
channel on adapter 0 and at the same time performing a scanning on
adapater 1. After the scan, though, glitches do not appear anymore. On
the other hand, there are no image glithces at all watching a channel
on adapter 1 and performing at the same time a scan on adapter0.
