Nice to know it works great. Should i pull the patch into the multiproto tree to make it easier, since it works as expected ? Also, can you test DVB-S2, a 30MSPS stream whether it works as expected ? (in case you have access to such a transponder ?) Currently, i have mixed results, so some amount of further test results would be quite nice >> Is it really isochronous transfer that the device really uses in it's >> default mode ?

Additionally, i plan to push out multiproto prior to mantis, so both in one tree will make it a bit messy.
