I don't use a remote with my PVR cards -- just my MVPs. One MVP came with the 34-button remote and the other one came with the 45-button. I can use either one with either MVP without issue. I know that doesn't answer the original question, but the 45-button remote should work fine for you, Benz.
As to the 34-button remote being older hardware, that is true. However, the MVP is still a model 1000 -- the newer MVP's just came with the newer remote. There was a bit of a problem with an older revision MVP overheating, but I don't think there will be many of those left on the market.
GBPVR system info intentionally left blank because I'm personally
insulted that you can't remember it from previous signatures.
