I got this recorder and noticed some aspects I consider as drawbacks that could possibly be solve with a firmware revision.
Dub HDD to DVD only allow for complete titles, so if you have a title longer than 1 hour you can not dub HQ+ to HQ quality, but using "auto" the recorder will try to fit to the size of the media (4.7GB) and the final quality will depend on the time of the recording.
If you record to DVD-RW you can make play lists that allow you to select just parts of the title, as as these are just pointers, you can reproduce just your selection.
You can not make play lists from HDD recordings.
Allowing play lists from HDD or the division of titles would make possible to back up to DVD at maximum quality, even if it was necessary to use more than one disc.
Other chance would be to allow DL discs to be recorded.
Firmware change could allow this.
Does someone know about previous firmware revisions made by Sony to this kind of equipment, either DVD recorders or players, in order to expand/change capabilities?
