Make sure you are doing a field render (lower field first for NTSC)

Like Mike sez. Check out this thread from the Discreet Edit forum:

No. The I/O cards from Aja, BMD, etc. are limited to what can be processed in the workstation’s CPU, and offer no additional hardware acceleration other than up/down/cross conversion in some models.

It’s storage and processor related. I’ve played 8-10 tracks of DV without dropping frames, but that was with a dual processor workstation and a 400 MB/s array.

You may be exporting your whole project with an orphan clip stuck out at the end of your timeline. Try exporting the work area only, or check your timeline for orphan clips.

I’d say the main reasons would be native file format handling, multiple stream HDV playback, real time effects, and accelerated render and export.

I have both the shuttle pro and the JL Cooper controllers. I must admit I don’t use them any more. I find the keyboard shortcuts easier. They do look kinda cool on the desk, though.

The major differences are:
1) Axio features SDI/HDSDI I/O. The RTX2 has analog I/O and FireWire only. (There is a handy DVI output on the RTX2 for monitoring purposes.)
2) Axio supports Full HD (1920×1080). The RTX2 supports up to 1440×1080, so it’s great for HDV, which is also 1440×1080.
3) Axio has XDCAM HD support (Both cards support HDV and DVCPRO/DVCPRO HD/P2)
4) Axio supports 10-Bit Uncompressed (RTX2 only does compressed; the compression rate on Axio can be set to a higher quality level than the RTX2)
5) Audio output on Axio is analog (XLR 6 ch.) or digital (8 ch. discrete outputs or embedded in SDI). RTX2 is RCA 2-ch. I/O.
6) The Axio LE breakout box is more professional, and supports simultaneous HD and down converted SD on seperate outputs.Other than that, the feature set is very similar. They share the same set of Matrox real time effects and the Premiere interface is nearly identical. Both systems will play back multiple tracks of native HDV in real time, and 8-10 tracks of DV in real time (storage speed permitting) with RT effects. Generally the storage requirements of Axio are much higher than the RTX2, adding to the system price. Also Axio really needs a dual processer workstation, whereas RTX2 is just fine with a single proc. workstation. That being said, both systems should be installed on a high end system with quad core processors and a decent graphics card like the ATI x1950 pro 512.

Honestly if I were confronted with these issues, I would do a clean install of everything on the C: drive. This will take less time than trying to hunt down the issue, and is more likely to fix the problem. Remove the Axio card beforehand, and don’t reinstall it until you have installed Premiere. When the found new hardware wizards open, point them to the Axio Utils folder. Then install the Axio software.
It is highly unlikely that the Axio card is bad. This sounds like a software corruption issue.
Double check the configuration for your workstation/motherboard on the Matrox website. Be sure to use the recommended slot for the card.

How far out of sync is it? The video could be delayed a few frames by the scalers built into the TV and the DVD player. Not too much you can do about that – perhaps you should feed SD video to the TV instead of upconverted video. There shouldn’t be a big difference in quality, and it may be a frame or two closer in sync, since you are bypassing the upconverter.
