No, there wouldn't be any difference. The only time you'd have a problem with this would be if the deck was out of alignment on either the record or playback device. I have had this problem on very cheap DV decsk, particularly JVC types, but that's a workshop-repairable fault in the equipment, not something you should expect.
If a tape has timecode recorded on it, it should be maintained through the firewire output even if the camera in question doesn't know how to decode or display it. DV timecode is embedded in the frame's image data and it would be much more work to remove it than it would just to let it go with the picture.
I'd be interested to hear if anyone had an instance of a cheap DV device that didn't output timecode known to be on a tape.

I could call the friend later today for the straight story.

Sigh, this again. Another FAQ candidate?
All DV has data space for the timecode, and every miniDV tape device I have ever used puts data into that space, even if it just starts from zero on a new tape. More professional DV equipment (including DVCAM and DVCPRO) usually offers additional features such as record or free-run timecode and the ability to set the start point, but at the most fundamental level, all DV has timecode.
If a post house has created DV dubs for you that do not include clone timecode, that post house is guilty of a fairly significant professional incompetence. To be fair, I do always make a point of asking specifically for clone timecode in situations like this, since it's a sad fact that many places consider DV to be an "amateur" format, and you often get nasty composite dubs as well, even from other digital formats. This situation irks me greatly, as there's no good technical reason for it other than the post house's superiority complex.
The overriding point here is that no matter how snooty they want to be about DV, they should be equipped and informed sufficiently to get this right. Boutiques as they may be, post houses are a service industry, they're working for the person who pays the bills and they owe that person competent work. I know of at least two places in London who are informed enough to do this work correctly (Metro Broadcast and Stanley Productions, and props to them both) and while it may mean you end up with a DV tape that was recorded on a DVCAM deck, it is possible to get it right - the other way to do it is with an SDI to Firewire convertor, or a component to firewire convertor that handles SMPTE/EBU audio-level timecode, and a real miniDV deck.
If you have been a victim of this problem, take the tapes back to the facility for a refund, as they quite simply have not done the job properly. If they trot out one of the standard "DV doesn't have timecode" lines, take your business elsewhere. As the specialists they are, they should know better.
For the record, this sort of nonsense slips into my personal ire list just below "we can't telecine to DVCAM" and just above "DVCAM is higher resolution than miniDV."

I tried to get in touch with my friend to find out what his experience was to see if my memory was wrong, but he must be away with the holidays and all.
But I do appreciate the time you took to spell it out. My professional strengths are in electric/lighting/production/film and not in the video/post world. My knowledge of DV is limited to my own shorts filmmaking in things shot on film and transferred to beta and dubbed to DV and DVcam, and stuff shot in mini DV, both edited with Final Cut, utilizing After Effects and the like. I do try and keep up with the higher level video camera tech specs and post routines, but until I get that work, the material doesn't seem to stick, no matter how much I throw against the wall.
So what I am basically saying is that I'm not an amatuer, but do need guidance from time to time in the areas I am not specialized in. So thanks in advance for your patience concerning all stupid questions I may post in the future. And the FAQ list would be a great idea. Perhaps even saving forums like cinematography.net (sorry Tim Tyler) would be a great way to go. But with the search feature here, that may be redundant.
