Vegas 5 Audio Glitches

I have been a user of Vegas for several years now, but I am a recording studio; I never really venture into the video aspect of the program except to maybe edit a little home movie or to convert an mpeg. I have become so used to the editing style and layout of Vegas that I just can't work as fast with Cubase, ProTools, Sonar, Logic, etc...
I had been using Vegas 3 for years and decided to upgrade to V5 as it now had automation. Long story short, the upgrade created huge problems on my computer, it was very glitchy and would put weird stutters during recording, and glitches and dropouts on playback of normal files. I reverted back to Vegas 3 and it was now corrupt as well. After reading a few posts from other users stating they had experienced similar problems going from V3 to V5, I completely reinstalled XP and setup my system according to a tweak guide created by someone using Vegas 5 and a very similar setup to my PC (P4 Intel 512M Ram). This made Vegas stable except for one very strange bug:
If I am recording a drum kit (10 or 12 channels of audio) through my 2 Delta 10/10 cards, it records fine, no glitches, plays back fine. The drummer only got the take right up until the chorus, so we record again, and then I edit the grouped waves of both takes, and slice them togther on the beat (maybe a real quick crossfade on one of the kick hits). Plays back fine. Then I close vegas, and oopen some other application, lets say Windows Media Player and watch a movie. Close Media Player and re-opn Vegas. Now, when it plays back, as it comes to that "crossfade" where the two takes overlap, it really stutters hard, hiccups a few times, and once its past the edit, it plays OK. This happen on all crossfades. But here is the strange bit - if I highlight the whole song, select loop plyback, and let the whole song loop through twice, it will glitch as I said on the first pass, but thereafter it is fine, no problems! So, I do have a stable system but I just have to play a song through once before it will behave - this gives clients a nervous moment at the start of our session, which I wish I didn't have to encounter.
I have tweaked the playback buffer setting to all possible values with no change. All my settings in my Delta card are fine, as I have done the same tests in Sonar and Cubase SX and they are rock solid, but as I mentioned my weapon of choice is Vegas so I really want to get it as good as these other appz. Also, when this glitch occurs - my CPU meter never goes above 30%.
Any advice? I have setup my computer according to all recommendations as to having a machine dedicated to digital video editing, I have enough CPU grunt, the harddrive is not fragmented, I always format a dedicated audio drive before a session, and only use 40 gig sized partitions. various brands of harddrive have not given any different results.
Thanks for any tips,
Adam B

C'mon, anyone?
Is this the forum hosted by Sony?
This is very annoying.

I'm with ya. I'm also trying to do away with my Cubase & ProTools and go solely with VEGAS. 1 application to master for all my needs! You can't beat that. I use the Echoe MIA... definitely wish I had the multi-in cad though. I'm keeping my eye on this thread.

Don't know if this will help but from what I've been reading on the forums V-5 requires much more ram than V3. The first play bad second play good sounds like ram. You will need some of the heavy hitters to answer your inquiry.

I'll trow in a thought. How does poor cache flushing sound to you guys? It seems something (Vegas itself?) occupies/steals memory from the playback process. When you loop the glitchy area it seems to behave exactly as when you do a dynamic RAM previem with video. You tell Vegas how much RAM to use in prefs. Then you loop-play an area until it plays smoothly. Can't elaborate any more...

You might post this in the Vegas AUDIO Forum, as well.
