Windows 7 - Transfer of video astoundingly slow to dvd

With the beta & RC I was getting transfer speeds burning avi, h.264 etc up to 10mbps. Thinking I had a bad spindle I am just now trying my second back up of some films and what not. Same difference.
I am getting 668 kps max. A transfer of 3.0 GB takes about 4 hours!

Anyone had this issue?
My Inspiron is also having this issue yet my old workhorse Dimension 9700 is fine. In other words both my laptops but not my single Pentium 4 pc.
BTW-I have Pro on my Studio, premium on the inspiron and the RC on the Dimension. Thought that was curious.
Love some feedback on this guys,
thanks,

Since the problem occurs on two different machines, I doubt that it is a problem, but I would run a test with HD Tune on the drives where the data is stored.

That seems unlikely but I'll try it. By HD Tune do you mean something outside of the 7 OS applications? My drive is smart enabled & reports via 7 & Belarc as Healthy.

Here is a link:

You don't need to buy it, the free version works fine. Smart doesn't report all problems, you need something like this to go deeper.

Thanks .I'll give it a try. One other thing I've been wondering about that might be corelated is that in the Beta one could choose to make a dvd seen as simply memory via the USB selection before burning. I Loved this feature (but wondered what it would do to the RW disc market.
Has Windows crippled this feature in the final build? That would be a real shame.
Thanks for the assistance,

Are you using the same DVDs on both PC?

Nope. Differant sets both times. Fujifilm currently (worked great on the beta & rc on BOTH laptops) and memorex. I had no prior experianced with them. They are color coded (my wife bought them so I figured they were the problem. It's bloody strange I tell ya.

It could be the speed on the DVDs. I have a stack of 4x DVDs laying around. I grabbed one by mistake and wondered why it took 2hrs to burn a Windows 7 iso.

No. They are both 16x

One other possibility is that your security program does extensive checking during the write. Put the CD burning program on the exclusion list of the security program or make a quick test turning the security program off.
