Hi Tasos, Are you sure 2.6.35-rc3 is working? The "fw_working" log doesn't appear to include any video transmission. For reference, a kernel log of successful video transmission is below. I used "dvgrab -noavc -guid 080046010261a1ff -d 1 -f avi /tmp/foo.avi" with a DCR-TRV120 in camera mode with no tape. (Of course, you would use -guid 00808801035809f1 with your GR-D20E.) Specifying the GUID prevents AV/C probing from cluttering the log. The computer reads '0900 oMPR and '0904 oPCR0 twice, and it sees that there is a broadcast connection on channel 63. At this time it will modify its own iPCR, but there is no Firewire transaction for this. Then the live video is received in a series of isochronous packets. Finally it reads oMPR and oPCR0 again - I don't know why. The dvgrab console output is ""/tmp/foo001.avi": 3.62 MiB 30 frames timecode 45:85:85.45 date 2024.01.17 02:09:26".
