I tried doing a DV tape to YesDVD transfer this weekend via firewire. I attached my 4-pin to 4-pin firewire cable to my Sony DV tape camcorder and to the DVR DV input, setup the source on the DVR as the DV input, and pre-erased a DVD+RW disc (because I have had no luck creating DVD-RW discs). I noticed a few problems doing this kind of direct transfer:
1) Upon selecting the RECORD button on the remote, the DV tape automatically began playing in the camcorder, but the record did not start immediately. First, a menu popped up asking where to write (HDD or DISC?). After I selected the DISC, there was another couple seconds of delay before the actual recoding began. So now I have lost several seconds at the beginning of the recording. I tried several different ways to get around this issue (including using the pause on my camcorder), but was unsuccessful in all attempts.
2) The recording froze for several seconds somewhere in the middle of the 1 hour transfer, but it did recover. Unfortunately, the tape continued to play of course, and those seconds were lost from the recording. I don't know if that was an issue with the DVR or with the tape. My LCD display on the camcorder played the interval just fine with no problems.
3) At the end of the tape, I pressed the STOP button on the DVR remote. A menu appeared asing if I wanted to create the YesDVD now, and I answered "NO". The manual states that additional segments may be added to a YesDVD (stated on the first page of the YesDVD section). I changed tapes in my camcorder, because I wanted to add another 15 minute segment to the disc. However, everytime I pressed the RECORD button on the remote to begin recording the new segment, I just received the circle with the slash (/). It would not append to my current disc!!! By the way, the disc was setup in the 2 hour recording mode, so there was plenty of space on the disc to add more recording. This was the most frustrating problem of all.
Has anyone tried to append to a "stopped" YesDVD disc with success?
