No, unfortunately not. Just as in the Windows driver the TS support was
completely dropped from both the firmware and the driver. As I
understand it the TS support in the firmware was never very good,
especially timecodes in the stream were unreliable. One company that
relied on TS actually switched to PS and use a PS2TS converter since
the card's TS wasn't good enough.
It is possible to resurrect TS, but it would require me to make a kernel
patch.

Likely. So many things changed that I no longer can remember
if /dev/video32 was also involved. The kernel contains a README.hm12 in
the Documentation/video4linux/cx2341x directory with example code and
HM12 format description.
